Such fibres are very t= hin glass wires with a diameter typically less than the wavelength of propa= gating light and they are fabricated using a heat-and-pull technique. They = can have very low propagation losses and are readily integrated with other = fibre devices. One significant feature of optical nanofibres is the very in= tense evanescent light field around them even for low propagation powers, m= aking them very useful for numerous applications. For example, optical nano= fibres can be used for micro and nanoparticle manipulation, as optical coup= lers for whispering gallery resonators, and for atom trapping and control. = I will discuss some of these applications with an emphasis on the versatili= ty of optical nanofibres as an experimental platform in (i) probing, manipu= lating, and trapping cold ground state and Rydberg neutral atoms for quantu= m technology applications and (ii) in microparticle manipulation for the ex= ploration of fundamental phenomena of non-paraxial light fields. ---------------------------------------------- Prof. Jiri Vala Department of Theoretical Physics Maynooth University Maynooth, Co.

This t= alk will be concerned with some of the many applications of ultrathin optic= al fibres made from commercial optical fibres. Such fibres are very thin gl= ass wires with a diameter typically less than the wavelength of propagating light and they are fabricated usin= g a heat-and-pull technique. They can have very low propagation losses and = are readily integrated with other fibre devices. One significant feature of= optical nanofibres is the very intense evanescent light field around them even for low propagation powers= , making them very useful for numerous applications. For example, optical n= anofibres can be used for micro and nanoparticle manipulation, as optical c= ouplers for whispering gallery resonators, and for atom trapping and control. I will discuss some of these applicatio= ns with an emphasis on the versatility of optical nanofibres as an experime= ntal platform in (i) probing, manipulating, and trapping cold ground state = and Rydberg neutral atoms for quantum technology applications and (ii) in microparticle manipulation for the exp= loration of fundamental phenomena of non-paraxial light fields.

It comprises all continuous densities aris= ing as solutions to a differential equation involving a vector of parameter= s.

Title: Estimating densities with asymm= etry and excess kurtosis

Abstract: Pearson's system is a rich c= lass of models that includes many classical univariate distributions. It co= mprises all continuous densities arising as solutions to a differential equ= ation involving a vector of parameters. The estimation of a Pearson density is challenging as small variations in = the parameters can induce wild changes in the shape of the corresponding de= nsity.

I will discuss how to estimate the vector of = parameters and the corresponding density effectively through a penalized li= kelihood procedure involving differential regularization. The approach comb= ines a penalized regression method and a profiled estimation technique. Simulations and an illustration with = S&P 500 data suggest that this method can improve market risk assessmen= t substantially through value-at-risk and expected shortfall estimates that= outperform those currently used by financial institutions and regulators.

Speaker: S. Gardiner

Title: Title: Boundary points of angular type form a set of zero harmonic measure


Date: Tue 11th October 2022

Time: 3:00PM

Location: Seminar Room SCN 1.25

Abstract:
(Joint work with Tomas Sjodin)

A boundary point w of a planar domain W is called 'angular' if there exists r > 0 such that each component of the set {z $\in$ W: |z-w| < r} which has w as a boundary point is contained in an angle of vertex w and aperture less than $\pi$. This talk will provide answers to the following problems that were submitted by Dvoretzky in 1974 to Hayman's collection of 'Research problems in function theory':
1) Prove, by non-probabilistic methods, that the set of angular boundary points of a planar domain has zero harmonic measure.
2) Does the same conclusion hold when angles less than pi are replaced by more general approach regions?
3) Is there a corresponding result in higher dimensions?

(Joint work with Tomas Sjodin)

Dear Colleagues,

 

You are welcome to the following seminar (details below). Coffee/tea and cake will be provided before the event at 3:30pm.

 

UCC Mathematical Sciences Seminar

 

Time and location: 4-5pm, Thursday 13th October, Western Gateway Building G16

 

Speaker: Piotr Suffczynski (University of Warsaw, Poland)

 

Title: Computational modeling of epileptic seizures with ion concentration dynamics

 

Abstract: Human and animal EEG data demonstrate that epileptic seizures are not stationary events but evolve with dynamics in the range of tens of seconds. We investigate the processes associated with seizure dynamics by complementing the Hodgkin-Huxley mathematical model with the physical laws that dictate ion movement. A computer model showed that seizure initiation, maintenance and autonomous termination can be explained by feedback mechanisms between ion concentration changes and neuronal activity. The model predicted a specific scaling law of inter-bursting intervals observed at the end of seizures, which was validated experimentally.

 

Best wishes,

Andrew Keane

Title: Rethinking programme and learni= ng design post-pandemic within the mathematical sciences

Abstract: There has been much discussi= on of late about =93Assessment and Feedback Design=94 which has been undoub= tedly amplified by the Covid-19 pandemic. Within the mathematical sciences,= the necessary transition from the use of traditional on-campus examinations as the dominant assessment mechanism= has perhaps attracted the greatest attention with one of the primary conce= rns being in relation to issues of academic integrity and fairness. Whilst = the pandemic necessitated us modifying the mechanism by which we were assessing student learning, it did not affo= rd the time or space to challenge ourselves as to why we are assessing stud= ent learning, and why we normally do so at a module rather than programme l= evel. More significantly, it did not allow us to question the fundamental relationship that exists between = student learning, assessment, and feedback and to ask whether this relation= ship has now changed from what we as mathematicians have previously underst= ood it to be.

As we move back to more normal times in terms of how we deliver our pr= ogrammes of study and support student learning, this forms an ideal time to= question this relationship. This session will not only explore what we hav= e learned about delivering teaching, administering assessment, and providing support during the pandemic, but i= t will explore the implications and opportunities for future programme deli= very.

out that the natural objects arising from Iwasawa theory have very differen=
t arithmetic behaviours depending on whether E has ordinary or supersingula=
r reduction at p. I will explain how these objects are defined and why cert=
ain of their properties depend on the reduction type of E at p.

This will be Prof Lei's second talk (in a series of 3). Final talk =
of this series is scheduled on October 20 (Thursday) at 2 pm (same location=

Abstract:

 

Understanding how anti-proliferative drug modulates = arterial healing following endovascular device deployment: a mathematical a= nd computational approach

 

Nowadays, it is taken for granted that stents are a = safe and effective treatment for obstructive coronary artery disease. = Clinical outcomes are good, but even with contemporary devices, repeat rev= ascularisation rates at 1 year are still at least 3-5%, increasing annually at a similar rate, with even higher rat= es in complex lesions such as bifurcations. Through the years there have be= en a number of innovations including thinner struts, more biocompatible all= oys, biodegradable coating and most recently bioresorbable scaffolds.   Despite the astronomical inv= estment, these have yielded only incremental improvements in patient outcom= e.  The most disruptive technology in the field remains, without doubt= , the incorporation of anti-proliferative drug to create drug-eluting stents (DES), with rates of restenosis (renarrowing= ) slashed from around 30% to 5%, compared with drug-free counterparts. In t= his talk, we reconsider the =91drug=92 aspect of DES and explore the potent= ial of driving down stubborn repeat revascularisation rates further through optimisation of the drug delivery = protocol.

Firstly, we present a series of mathematical models = of varying complexity to model the effect of drugs on smooth muscle cell pr= oliferation in an in-vitro environment, and make comparisons with experimen= tal data. Our results highlight that, at least for Sodium Salicylate and Paclitaxel, the current state-of-the-ar= t nonlinear saturable binding model is incapable of capturing the prolifera= tive response of SMCs across a range of drug doses and exposure times [1].<= o:p>

Next, moving towards the in vivo situation, a novel = continuum model of tissue growth coupled with spatiotemporal delivery of dr= ug is presented in order to simulate the response of the artery to stenting= . Our results indicate that the severity and time-course of restenosis is critically dependent on the drug delivery= strategy.  Specifically, we uncover an intricate interplay between in= itial drug loading, drug release rate and restenosis, indicating that it is= not sufficient to simply ramp-up the drug dose or prolong the time course of drug release to improve stent effi= cacy [2].

Finally, some preliminary work is presented that con= siders the incorporation of disease (from intravascular imaging) within our= models of stent drug release and tissue transport, motivating the need for= a more tailored drug-delivery strategy.

Title: Rethinking programme and learni= ng design post-pandemic within the mathematical sciences

Abstract: There has been much discussi= on of late about =93Assessment and Feedback Design=94 which has been undoub= tedly amplified by the Covid-19 pandemic. Within the mathematical sciences,= the necessary transition from the use of traditional on-campus examinations as the dominant assessment mechanism= has perhaps attracted the greatest attention with one of the primary conce= rns being in relation to issues of academic integrity and fairness. Whilst = the pandemic necessitated us modifying the mechanism by which we were assessing student learning, it did not affo= rd the time or space to challenge ourselves as to why we are assessing stud= ent learning, and why we normally do so at a module rather than programme l= evel. More significantly, it did not allow us to question the fundamental relationship that exists between = student learning, assessment, and feedback and to ask whether this relation= ship has now changed from what we as mathematicians have previously underst= ood it to be.

As we move back to more normal times in terms= of how we deliver our programmes of study and support student learning, th= is forms an ideal time to question this relationship. This session will not= only explore what we have learned about delivering teaching, administering assessment, and providing support= during the pandemic, but it will explore the implications and opportunitie= s for future programme delivery.

Clinical outcomes are good, but even with contemporary devices, repeat revascularisation rates at 1 year are still at least 3-5%, increasing annually at a similar rate, with even higher rates in complex lesions such as bifurcations. Through the years there have been a number of innovations including thinner struts, more biocompatible alloys, biodegradable coating and most recently bioresorbable scaffolds. Despite the astronomical investment, these have yielded only incremental improvements in patient outcome. The most disruptive technology in the field remains, without doubt, the incorporation of anti-proliferative drug to create drug-eluting stents (DES), with rates of restenosis (renarrowing) slashed from around 30% to 5%, compared with drug-free counterparts. In this talk, we reconsider the =E2=80=98drug=E2=80=99 aspect of DES and explore the potential of driving d= own stubborn repeat revascularisation rates further through optimisation of the drug delivery protocol. Firstly, we present a series of mathematical models of varying complexity to model the effect of drugs on smooth muscle cell proliferation in an in-vitro environment, and make comparisons with experimental data.

Our results indicate that the severity and time-course of restenosis is critically dependent on the drug delivery strategy. Specifically, we uncover an intricate interplay between initial drug loading, drug release rate and restenosis, indicating that it is not sufficient to simply ramp-up the drug dose or prolong the time course of drug release to improve stent efficacy [2].

Abstract:=
Following a chemical we= apons attack, it is crucial for public health that the toxic chemical agent= is properly cleaned up. One particular issue is when the agent has contaminated porous materials, such as brick o= r concrete. In such cases, decontamination is typically achieved by neutral= ising the agent with a cleanser in a chemical reaction. It is relatively st= raightforward to write down a model that describes the interplay of the agent and cleanser on the scale of the= pores, but very computationally expensive to solve such a model over reali= stic spill sizes. In this talk I will present homogenised models for the re= active decontamination of porous media, which are computationally efficient to simulate while still taking = the pore-scale behaviour into account. Solutions of these homogenised model= s show how differences in the initial distribution of agent affect both the= decontamination time and the amount of cleanser required to fully decontaminate the porous material.

Studies based on models of QCD such as NJL or quark-meson models do show such phases, however, no unambiguous confirmation that they happen in QCD has been achieved yet. In this talk, I will review the current state of the search for inhomogeneities and discuss the first attempts to perform a QCD-based stability analysis for such phenomena.

I will show that in low energies it is possible to obtain a confined, stable phase in the matrix model and how this is interpreted as a gas of supergravitons in 11D spacetime. The confinement/deconfinement transition is interpreted as a topology change on the gravity side. The deconfined phase can also be studied in low temperatures and I will show that by using the deformed D0-matrix model (BMN) where one is able to better test the gauge/gravity duality with small stringy corrections where a supergravity dual is analytically known and valid. Furthermore, if time permits, I will argue that the role of the singlet and non-singlet sectors in the contributions to the partition functions are almost the same in these low temperatures presenting theoretical arguments and numerical verifications. With best wishes, Denjoe. --111151493-1279540757-1665572207=:572698-- From owner-mathdep LISTSERV.HEANET.IE Wed Oct 12 12:18:37 2022 Return-Path: X-Spam-Checker-Version: SpamAssassin 3.4.0 (2014-02-07) on maths.ucd.ie X-Spam-Level: X-Spam-Status: No, score=0.5 required=5.0 tests=DKIM_ADSP_CUSTOM_MED, FREEMAIL_FORGED_FROMDOMAIN,FREEMAIL_FROM,HEADER_FROM_DIFFERENT_DOMAINS, HTML_MESSAGE,MAILING_LIST_MULTI,SPF_HELO_NONE,SPF_SOFTFAIL, T_SCC_BODY_TEXT_LINE autolearn=no autolearn_force=no version=3.4.0 References: Content-Type: multipart/alternative; boundary="0000000000004913c305ead488d5" Message-ID: Date: Wed, 12 Oct 2022 12:13:44 +0100 Reply-To: Seminars Maths NUIG Sender: UCD Maths Department Distribution List From: Seminars Maths NUIG Subject: Maths: Seminar Uni Galway Thursday 13th of October at 3pm To: MATHDEP LISTSERV.HEANET.IE In-Reply-To: Precedence: list List-Help: , List-Unsubscribe: List-Subscribe: List-Owner: Status: O X-Status: X-Keywords: X-UID: 28 --0000000000004913c305ead488d5 Content-Type: text/plain; charset="UTF-8" Content-Transfer-Encoding: quoted-printable University of Galway Maths Seminar Speaker: Sean McGinty (University of Glasgow) Title: Understanding how anti-proliferative drug modulates arterial healing following endovascular device deployment: a mathematical and computational approach Date: Thursday 13th of October at 3pm Time: 3:00pm Location: Alice Perry Engineering Building Rm 3052 Abstract: Understanding how anti-proliferative drug modulates arterial healing following endovascular device deployment: a mathematical and computational approach Nowadays, it is taken for granted that stents are a safe and effective treatment for obstructive coronary artery disease. Clinical outcomes are good, but even with contemporary devices, repeat revascularisation rates at 1 year are still at least 3-5%, increasing annually at a similar rate, with even higher rates in complex lesions such as bifurcations. Through the years there have been a number of innovations including thinner struts, more biocompatible alloys, biodegradable coating and most recently bioresorbable scaffolds. Despite the astronomical investment, these have yielded only incremental improvements in patient outcome. The most disruptive technology in the field remains, without doubt, the incorporation of anti-proliferative drug to create drug-eluting stents (DES), with rates of restenosis (renarrowing) slashed from around 30% to 5%, compared with drug-free counterparts. In this talk, we reconsider the =E2=80=98drug=E2=80=99 aspect of DES and explore the potential of driving d= own stubborn repeat revascularisation rates further through optimisation of the drug delivery protocol. Firstly, we present a series of mathematical models of varying complexity to model the effect of drugs on smooth muscle cell proliferation in an in-vitro environment, and make comparisons with experimental data. Our results highlight that, at least for Sodium Salicylate and Paclitaxel, the current state-of-the-art nonlinear saturable binding model is incapable of capturing the proliferative response of SMCs across a range of drug doses and exposure times [1]. Next, moving towards the in vivo situation, a novel continuum model of tissue growth coupled with spatiotemporal delivery of drug is presented in order to simulate the response of the artery to stenting. Our results indicate that the severity and time-course of restenosis is critically dependent on the drug delivery strategy. Specifically, we uncover an intricate interplay between initial drug loading, drug release rate and restenosis, indicating that it is not sufficient to simply ramp-up the drug dose or prolong the time course of drug release to improve stent efficacy [2].

Abstract:

<= br>Understanding how anti-proliferative drug modulates arterial healing fol= lowing endovascular device deployment: a mathematical and computational app= roach
=C2=A0
Nowadays, it is taken for granted that stents are a safe= and effective treatment for obstructive coronary artery disease.=C2=A0 Cli= nical outcomes are good, but even with contemporary devices, repeat revascu= larisation rates at 1 year are still at least 3-5%, increasing annually at = a similar rate, with even higher rates in complex lesions such as bifurcati= ons. Through the years there have been a number of innovations including th= inner struts, more biocompatible alloys, biodegradable coating and most rec= ently bioresorbable scaffolds. =C2=A0 Despite the astronomical investment, = these have yielded only incremental improvements in patient outcome.=C2=A0 = The most disruptive technology in the field remains, without doubt, the inc= orporation of anti-proliferative drug to create drug-eluting stents (DES), = with rates of restenosis (renarrowing) slashed from around 30% to 5%, compa= red with drug-free counterparts. In this talk, we reconsider the =E2=80=98d= rug=E2=80=99 aspect of DES and explore the potential of driving down stubbo= rn repeat revascularisation rates further through optimisation of the drug = delivery protocol.
=C2=A0
Firstly, we present a series of mathematica= l models of varying complexity to model the effect of drugs on smooth muscl= e cell proliferation in an in-vitro environment, and make comparisons with = experimental data. Our results highlight that, at least for Sodium Salicyla= te and Paclitaxel, the current state-of-the-art nonlinear saturable binding= model is incapable of capturing the proliferative response of SMCs across = a range of drug doses and exposure times [1].
=C2=A0
Next, moving tow= ards the in vivo situation, a novel continuum model of tissue growth couple= d with spatiotemporal delivery of drug is presented in order to simulate th= e response of the artery to stenting. Our results indicate that the severit= y and time-course of restenosis is critically dependent on the drug deliver= y strategy.=C2=A0 Specifically, we uncover an intricate interplay between i= nitial drug loading, drug release rate and restenosis, indicating that it i= s not sufficient to simply ramp-up the drug dose or prolong the time course= of drug release to improve stent efficacy [2].
=C2=A0
Finally, some = preliminary work is presented that considers the incorporation of disease (= from intravascular imaging) within our models of stent drug release and tis= sue transport, motivating the need for a more tailored drug-delivery strate= gy.

Title: Hedging = Portfolio for a Market Model of Degenerate Diffusions

 

= Abstract: We consider a semimarting= ale market model when the underlying diffusion has a singular volatility ma= trix and compute the hedging portfolio for a given payoff function. Recentl= y, the representation problem for such  degenerate diffusions as a stochastic integral with respect to a martingal= e has been completely settled. This  representation and  Malliavi= n calculus established further for the functionals of a degenerate diffusio= n process  constitute the basis of the present work. Using the Clark-Hausmann-Bismut-Ocone type representation formula de= rived for these functionals, we prove a version of this formula under an eq= uivalent martingale measure. This allows us to derive the hedging portfolio=   as a  solution of a system of linear equations. This is joint work with I. Demirel and S.A. Ustunel.

Title: The false dilemma: Bayesian vs = Classical Statistics

Abstract: There are two main opposing = schools of statistical reasoning: classical and Bayesian. Classical statist= ics is entirely based on the philosophical view of science of Karl Popper, = in which a scientific hypothesis can not be proved, but only disproved (the Falsification Principle). The so-ca= lled Hypothetico-Deductive method of Popper is well-founded in the (frequen= tist) probability theory of Andrey Kolmogorov, and in the statistical works= of Ronald Fisher, Karl Pearson, Jerzy Neyman, among many others. Although Classical statistics is consider= ed the "standard" for scientific practice and statistical teachin= g, the Bayesian approach is quickly gaining ground. For this reason, the Ba= yesian vs Classical debate emerges frequently in the statistical community, with each side blaming the methodological fl= aws of one another. However, this debate should not be on the methodologica= l level, but rather on the philosophical level. Contrary to general consent= , Bayesian statistics is not suited to the Popperian view of science. In this lecture, we will show alternativ= e views of the scientific method, as well as alternative views of probabili= ty (such as probability as an extension of logic, as defined by Richard Cox= and Edwin Jaynes), which makes Bayesian reasoning appear as a genuinely scientific approach, rather than = a mere "opponent" of Classical statistics.

Disclaimer: the title of this talk was freely= inspired by the title of the article by Jordi Vallverd=FA, "The False= Dilemma: Bayesian vs. Frequentist", published in the Electronic Journ= al for Philosophy in 2008. I will also talk about why I changed "frequentist" to "classical".

This relation, dubbed the double copy, is broader than originally envisioned and explorations of its applicability are still underway. In this talk, I will focus on extensions of the double copy relation for massive mediators. I will show that a surprising example arises in 3d when considering topologically massive theories. To show its robustness, I will present different scenarios where this double copy holds, including classical realizations and a derivation from minitwistor space.

Abstract: There are two main opposing = schools of statistical reasoning: classical and Bayesian.

The so-ca= lled Hypothetico-Deductive method of Popper is well-founded in the (frequen= tist) probability theory of Andrey Kolmogorov, and in the statistical works= of Ronald Fisher, Karl Pearson, Jerzy Neyman, among many others. Although Classical statistics is consider= ed the "standard" for scientific practice and statistical teachin= g, the Bayesian approach is quickly gaining ground. For this reason, the Ba= yesian vs Classical debate emerges frequently in the statistical community, with each side blaming the methodological fl= aws of one another. However, this debate should not be on the methodologica= l level, but rather on the philosophical level. Contrary to general consent= , Bayesian statistics is not suited to the Popperian view of science.

Speaker: Hermann Render

Title: Fischer decomposition for entire functions and the Dirichlet problem for unbounded quadratic surfaces


Date: Tue 25th October 2022

Time: 3:00PM

Location: Seminar Room SCN 1.25

Abstract: Let $P_{2k}$ be a homogeneous non-negative polynomial of degree 2k and
assume that $P_j £ for j$=0,...,\beta <2k$ are homogeneous polynomials of degree $j$.
Further a certain integral inequality depending on a parameter \alpha and $P_2k$ is assumed which
is valid for all homogeneous polynomials of degree m.

The main result of the talk states that for any entire function f of order

$\rho < ( 2k-\beta ) / \alpha$ there exist entire functions $q$ and $r$

of finite order with


$f= ( P_2k-P_\beta -....-P_0 ) q+r$ and $\Delta ^{k}r=0$


where $\Delta$ is the Laplace operator.


This result is used to establish the existence of entire harmonic solutions

of the Dirichlet problem for cylinders and parabola-shaped domains for data

given by entire functions of order smaller than $1$ and $1/2$ respectively.

In this talk we shall present applications of the Fischer inner product to boundary value problems with respect to a homogeneous partial differential operator $P*(D)$ (e.g. the Goursat problem). We shall present a short proof of the Fischer decomposition for polynomials and a generalization of H.S. Shapiro for the Fischer decomposition for entire functions. These results can be interpreted as finding the solutions of the equation $P*(D)f=0$ with respect to boundary values given on the zero set of the homogeneous polynomial $P(x)$. Main aim of the talk is to discuss the more difficult problem when the boundary values are given on the zero set of $P(x)+r(x)$ where $r(x)$ s a polynomial of lower degree than $P(x)$.

is a useful tool in theory of s= pherical harmonics.=C2=A0=C2=A0
In this talk we shall present applications of the Fischer i= nner product to=C2=A0 boundary value problems=C2=A0
with respect to a homogeneous partial d= ifferential operator $P*(D)$ (e.g. the Goursat problem).=C2=A0
We shall present a short pro= of of the Fischer decomposition for=C2=A0
polynomials and a generalization of H.S. Shapiro = for the Fischer=C2=A0
decomposition for entire functions.=C2=A0 These results can be interp= reted as=C2=A0
f= inding the solutions of the equation=C2=A0 $P*(D)f=3D0$=C2=A0 with respect = to boundary values=C2=A0
given on the zero set of the homogeneous polynomial $P(x)$.=C2=A0= =C2=A0
Main aim = of the talk is to discuss the more difficult problem
when the boundary values are given on = the zero set of $P(x)+r(x)$
where=C2=A0 $r(x)$=C2=A0 s a polynomial of lower degree th= an $P(x)$.=C2=A0=C2=A0

Title: Geometry of Ideal Fluid Motion<= /div>

Abstract: V. Arnold observed in his se= minal paper that solutions of the Euler equations for ideal fluid motion ca= n be viewed as geodesics of a certain right-invariant metric on the group o= f volume-preserving diffeomorphisms. In their celebrated paper Ebin and Marsden provided the formulation of the= above in the H^s Sobolev setting. Here they proved that the space of H^s v= olumorphisms can be given the structure of a smooth, infinite dimensional H= ilbert manifold. They illustrated that, when equipped with a right-invariant L^2 metric, the geodesic equati= on on this manifold is a smooth ordinary differential equation. They then a= pplied the classic iteration method of Picard to obtain existence, uniquene= ss and smooth dependence on initial conditions. In particular, the last property allows one to define a smooth= exponential map on the group of volumorphisms in analogy with the classica= l construction in finite dimensional Riemannian geometry. Hence, the work o= f Arnold, Ebin and Marsden allows one to explore questions of ideal fluid motion armed with tools from Riema= nnian geometry. In this talk I will present some results about the behaviou= r of geodesics on these Hilbert manifolds, when they are framed as solution= s to a two-point boundary value problem and introduce some questions relating to current work.

Dear Colleagues,

Title: Fract= al spheres, visual metrics, and rational maps

 

Abstract:<= /b>

Quasisymmetric maps map ratios of distances in a controlled way. Th= ey generalize conformal maps. The quasisymmetric uniformization theorem ask= s if a certain metric space is quasisymmetrically equivalent to some model space. Of particular interest in this context is = the question to characterize quasispheres, i.e., metric spaces that are qua= sisymmetrically equivalent to the standard 2-sphere. A simple class of frac= tal spheres are “snowballs”, which are topologically 2-dimensional analogues of the van Koch snowflake curve.=  

 

A Thurston map is a topological analogue of a rational map (i.e., a= holomorphic self-map of the Riemann sphere). Thurston gave a criterion whe= n such a map “is” rational. Given such a map $f$ that is expanding, we can equip the sphere with a “visual = metric”. With respect to this metric, the sphere is a quasisphere if = and only if $f$ ``is'' rational.

 

This is joint work with Mario Bonk (UCLA).

Arnold observed in his seminal paper that solutions of the Eul= er equations for ideal fluid motion can be viewed as geodesics of a certain= right-invariant metric on the group of volume-preserving diffeomorphisms. = In their celebrated paper Ebin and Marsden provided the formulation of the = above in the H^s Sobolev setting.

Title: Geometry of Ideal Fluid Motion<= /div>

Abstract: V. Arnold observed in his se= minal paper that solutions of the Euler equations for ideal fluid motion ca= n be viewed as geodesics of a certain right-invariant metric on the group o= f volume-preserving diffeomorphisms. In their celebrated paper Ebin and Marsden provided the formulation of the= above in the H^s Sobolev setting. Here they proved that the space of H^s v= olumorphisms can be given the structure of a smooth, infinite dimensional H= ilbert manifold. They illustrated that, when equipped with a right-invariant L^2 metric, the geodesic equati= on on this manifold is a smooth ordinary differential equation. They then a= pplied the classic iteration method of Picard to obtain existence, uniquene= ss and smooth dependence on initial conditions. In particular, the last property allows one to define a smooth= exponential map on the group of volumorphisms in analogy with the classica= l construction in finite dimensional Riemannian geometry. Hence, the work o= f Arnold, Ebin and Marsden allows one to explore questions of ideal fluid motion armed with tools from Riema= nnian geometry. In this talk I will present some results about the behaviou= r of geodesics on these Hilbert manifolds, when they are framed as solution= s to a two-point boundary value problem and introduce some questions relating to current work.

Seminar Speaker: Jeroen van Dongen (University of Amsterdam) Title: Einstein's black hole When: Friday, October 28, 2022 - 14:00 to 15:00 Where: Hall A, Arts Building, Maynooth University North Campus (+Zoom) In September 1939, the paper that is now celebrated as the seed of the modern conception of a black hole was published by Robert Oppenheimer and his student Hartland Snyder: in it, they argued that a star may collapse without ever reaching a new equilibrium state, beyond its gravitational radius; it will become so dense that not even light emitted at its surface will escape. Just one month after Oppenheimer and Snyder's paper appeared, Albert Einstein authored another article in which he argued that there was a limit to how much matter could be concentrated in a spacetime, and that as a consequence no "Schwarzschild singularity" would ever appear in nature. Did Einstein intend to argue against Oppenheimer and Snyder, without even citing their work? Did he even know of their paper, or is it a coincidence that the papers appeared so close to one another? And how are differences of opinion to be understood in the light of how these authors understood general covariance and the dynamics of spacetime? Using novel sources, we will address these questions, and try to answer how much in particular Einstein and his close colleagues knew of the way towards the unknowable: the path into the black hole (joint work with Dennis Lehmkuhl).

In short, for fundamental deformations in the structure of spacetime, quantum mechanics necessitates the creation of thermalized particles from the vacuum. One such phenomenon, known as the Unruh effect, causes empty space to effervesce a thermal bath of particles when viewed by an observer undergoing uniformly accelerated motion. These highly accelerated systems will also have an associated Rindler horizon which produces this Unruh radiation at the celebrated Fulling-Davies-Unruh temperature. For accelerated charges, the emission and absorption of this Unruh radiation will imprint the FDU temperature on any photons emitted and subsequently detected in the laboratory. A recent series of high energy channeling experiments carried out by the NA63 collaboration at CERN have finally brought about the first observations and insights into the nature of the Unruh effect. In this presentation, I will discuss the various aspects of acceleration-induced thermality measured by these experiments at NA63. With best wishes, Denjoe.

Title: Fractal spheres, visual metrics, and rational maps


Date: Tue 1st November 2022

Time: 4:00PM

Location: Seminar Room SCN 1.25

Abstract: Quasisymmetric maps map ratios of distances in a controlled way. They generalize conformal maps. The quasisymmetric uniformization theorem asks if a certain metric space is quasisymmetrically equivalent to some model space. Of particular interest in this context is the question to characterize quasispheres, i.e., metric spaces that are quasisymmetrically equivalent to the standard $2$-sphere. A simple class of fractal spheres are ``snowballs', which are topologically $2$-dimensional analogs of the van Koch snowflake curve.
A Thurston map is a topological analog of a rational map (i.e., a holomorphic self-map of the Riemann sphere). Thurston gave a criterion when such a map ``is' rational. Given such a map $f$ that is expanding, we can equip the sphere with a ``visual metric'. With respect to this metric, the sphere is a quasisphere if and only if $f$ ``is' rational.

This is joint work with Mario Bonk (UCLA).

=E2=80=9Dno-arbitrage=E2=80=9D in classical math= ematical finance with =E2=80=9Dno-=CF=81-arbitrage=E2=80=9D. The model we c= onsider
is static and frictionless, and the obtained price bounds can be= sharp enough to be useful in the
practise of pricing. This is joint wor= k with Martin Herdegen.

Speaker: Dr. Matt Butler (School of Mathematics, University of Birmingham, = U.K.). Title: Controlling microscale systems with fluid-induced deformation Abstract: Although deformation of solids is often seen as a negative trait (e.g. fail= ure through buckling, twisting and warping), recent work has shown that kno= wledge of elastic behaviour can be exploited to achieve positive outcomes. = One area where this is becoming increasingly prevalent is in microsystems. = At these small scales, the dominant physics is different to everyday experi= ence and new mechanisms are needed to complete simple tasks such as swimmin= g, gripping, sorting and transporting. Designed structures or components th= at distort in pre-specified ways are a promising mechanism to achieve some = of these goals. In this talk, I will explore two distinct, useful ways that fluids are able= to deform compliant solid structures: elasto-capillary adhesion and hydrog= el swelling. I will first discuss how adhesion forces due to surface tensio= n can be enhanced and controlled by the addition of deformable structures, = before explaining how certain swelling and shrinking hydrogels behave when = actuated to change size and how this control of their size can be used to c= reate shape-changing structures.

Title: Controlling microscale systems with fluid-induced deform= ation

Abstract:
Although deformation of solids is often seen as a negative trait (e.g.= failure through buckling, twisting and warping), recent work has shown that knowledge of elastic behaviour ca= n be exploited to achieve positive outcomes. One area where this is becomin= g increasingly prevalent is in microsystems. At these small scales, the dom= inant physics is different to everyday experience and new mechanisms are needed to complete simple tasks such as = swimming, gripping, sorting and transporting. Designed structures or compon= ents that distort in pre-specified ways are a promising mechanism to achiev= e some of these goals.
In this talk, I will explore two distinct, useful ways that fluids are= able to deform compliant solid structures: elasto-capillary adhesion and hydrogel swelling. I will first discuss how = adhesion forces due to surface tension can be enhanced and controlled by th= e addition of deformable structures, before explaining how certain swelling= and shrinking hydrogels behave when actuated to change size and how this control of their size can be use= d to create shape-changing structures. Comprehension of these fundamental m= odel systems can ultimately help us develop new microtechnologies, as well = as improve existing devices.

A Minoan town was covered by five meters of pumice and volcanic ash, which preserved paintings as colorful and accomplished as those of Pompeii. For decades the exact time of the eruption and its historical significance is the topic of heated controversies among archaeologists, historians and geologists. Mike Baillie from QUB jumped in the middle of the fray with an attack on the methodology of all teams who had identified the volcanic signals in ice cores. He was right. The huge volcanic eruption in winter 1628/27 BC was not due to Santorini, but to the Aniakchak volcano in the Aleutian island chain. Its site is equally impressive, a National Monument of the USA, but little known by the public due to its location in Alaska. For history it is as significant as Santorini, because it provided exact dates for Babylonian chronology. The Santorini eruption happened three quarters of a century later, but its exact time is still unknown. There is a long-standing controversy about its possible link to the Egyptian 'Tempest Stele'. Some think that its text was purely symbolic, because no eruption could cause a tempest in all of Egypt. This is true, but it will be argued that the name of the stele is a misnomer. What it really is about is the volcanic boom that was heard all over the Nile valley. It was understood as a signal that the natural order was breaking down and led to a social upheaval. The young pharaoh Ahmose was up to the challenge. Using unarmed soldiers and sufficient money, he quickly restored order. -- Mr. George Rogers | Librarian & School Administrator School of Theoretical Physics Dublin Institute for Advanced Studies 10 Burlington Road, Dublin 4 - D04 C932 Tel: +353-1-6140104 www.dias.ie #DIASdiscovers https://twitter.com/StpDias https://facebook.com/stp.dias -- This email and any files transmitted with it are confidential and intended solely for the use of the individual or entity to whom they are addressed.

Statutory Public Lecture hosted by Trinity College, Dublin. Speaker: Werner Nahm (DIAS) Title: ‘A Tale of Two Volcanoes’ Date & Time: Monday 14 November, 6:30-8pm Venue: Robert Emmet Theatre, Arts Block, Trinity College, Dublin Book Tickets: https://www.eventbrite.com/e/stp-dias-statutory-public-lecture-2022-a-tale-of-two-volcanoes-tickets-452991920027 Abstract: The volcanic caldera of the Santorini island is one of the most impressive sites in Europe, equally important for tourism, science and history. A Minoan town was covered by five meters of pumice and volcanic ash, which preserved paintings as colourful and accomplished as those of Pompeii. For decades the exact time of the eruption and its historical significance is the topic of heated controversies among archaeologists, historians and geologists. Mike Baillie from QUB jumped in the middle of the fray with an attack on the methodology of all teams who had identified the volcanic signals in ice cores. He was right. The huge volcanic eruption in winter 1628/27 BC was not due to Santorini, but to the Aniakchak volcano in the Aleutian island chain. Its site is equally impressive, a National Monument of the USA, but little known by the public due to its location in Alaska. For history it is as significant as Santorini, because it provided exact dates for Babylonian chronology. The Santorini eruption happened three quarters of a century later, but its exact time is still unknown. There is a long-standing controversy about its possible link to the Egyptian 'Tempest Stele'. Some think that its text was purely symbolic, because no eruption could cause a tempest in all of Egypt. This is true, but it will be argued that the name of the stele is a misnomer. What it really is about is the volcanic boom that was heard all over the Nile valley. It was understood as a signal that the natural order was breaking down and led to a social upheaval. The young pharaoh Ahmose was up to the challenge. Using unarmed soldiers and sufficient money, he quickly restored order. -- Mr. George Rogers | Librarian & School Administrator School of Theoretical Physics Dublin Institute for Advanced Studies 10 Burlington Road, Dublin 4 - D04 C932 Tel: +353-1-6140104 www.dias.ie #DIASdiscovers https://twitter.com/StpDias https://facebook.com/stp.dias -- This email and any files transmitted with it are confidential and intended solely for the use of the individual or entity to whom they are addressed.

  Abstract:=
    Numerical calculations of lattice regularized QFTs are a powerful to=
ol to understand such theories when analytic methods are not applicable. Ho=
wever, the utility of numerical results can be affected by two issues: (i) =
calculations are necessarily performed in a finite-volume spacetime and (ii=
) imaginary-time correlation functions are evaluated. Both aspects play an =
especially important role for multi-particle observables including scatteri=
ng and decay amplitudes and inclusive rates. In this colloquium, I will dis=
cuss progress for extracting such observables from numerical lattice field =
theory based on two strategies. One is to use the finite-volume as a tool, =
rather than an unwanted artefact, and to apply generic field theoretic rela=
tions between finite-volume quantities and infinite-volume amplitudes. The =
second is to carefully regulate the inverse Laplace transform, in order to =

The Formation of Karst Pinnacles

Dr Nicholas Moore

Thu Oct 5, 15:00-16:00

Lecture held in ADB1020

Abstract: Recent experiments demonstrate how dissolution, in conjunction with gravitationally-induced convective flows, can create sharp geometric features. These laboratory-created structures give insight into geological features known as karst pinnacles. A new computational approach, specially tailored to the hyberbolic nature of the underlying PDEs, reveals convergence to a morphological attractor with high, yet finite, tip curvature. These results reverse previous hypotheses on shock formation (i.e. finite-time blowup of tip curvature), agree well with laboratory experiments, and enable simple estimates for the age of geological structures.

Title: Pattern-based prediction of population= outbreaks

Abstract: The complexity and practical importance of insect outbreaks have = made the problem of predicting outbreaks a focus of recent research. We pro= pose the Pattern-Based Prediction (PBP) method for predicting population ou= tbreaks. It uses information on previous time series values that precede an outbreak event as predictors o= f future outbreaks, which can be helpful when monitoring pest species. We i= llustrate the methodology using simulated datasets and an aphid time series= obtained in wheat crops in Southern Brazil. We obtained an average test accuracy of 84.6% in the simulation st= udies implemented with stochastic models and 95.0% for predicting outbreaks= using a time series of aphids in wheat crops in Southern Brazil. Our resul= ts show the PBP method=92s feasibility in predicting population outbreaks. We benchmarked our results against est= ablished state-of-the-art machine learning methods: Support Vector Machines= , Deep Neural Networks, Long Short Term Memory and Random Forests. The PBP = method yielded a competitive performance associated with higher true-positive rates in most comparisons while provi= ding interpretability rather than being a black-box method. It is an improv= ement over current state-of-the-art machine learning tools, especially by n= on-specialists, such as ecologists aiming to use a quantitative approach for pest monitoring. We provide the = implemented PBP method in Python through the pypbp package.

Title: The Library of Irish Mathematics

Abstract: The online Annals of Irish Mathemat= ics & Mathematicians documents over 5300 mathematical people who are/we= re Irish, work(ed) in Ireland, or had Irish doctoral advisors.

It also documents many hundreds of books writ= ten or edited by people in the first two categories, spanning 320 years. &n= bsp;The reach is broad, including mathematical physics, statistics,  a= nd more.

From geometry, number theory, algebra, real a= nd complex functions, DEs, fluid mechanics, relativity, and quantum theory,= to astronomy, actuarial maths, and maths education, it all adds up to a ve= ry impressive contribution.  

We will provide an overview of the wealth and= diversity of tomes to be found in this islandwide "virtual library of= Irish mathematics."

The evidence is very clear that Ireland has a= lways punched
well above its weight in this arena.

Pure and applied maths, theoretical physics, stats= , maths ed, actuarial maths, engineering maths, maths history & biograp= hy, etc.

Authors who are Irish or Irish trained (w= orking anywhere) or people based in Ireland when the book was published.

It's currently=C2=A0focussed mostly on third=C2= =A0level, research, historical and popular exposition=C2=A0tomes.=C2=A0 We = know that we need to add many school books from the last century.
=

Such "post 2020" tomes are also items to feat= ure in the next Irish Maths Wall Calendar (if we have not already=C2=A0done= so recently).

Please scroll down to the end of th= e green table in https://www= .cardcolm.org/AIMB.html (there is a slider bar specifically for the tab= le).

What have we=C2=A0missed?=C2=A0=C2=A0<= /div>

We also=C2=A0welcome missing information on volume= s from 2020 or earlier.

Thank you

title: Intrinsic Mirror Symmetry
abstract: Mirror symmetry was a phenomenon = discovered by physicists around 1989: they observed that certain kinds of= six-dimensional geometric objects known as Calabi-Yau manifolds seemed t= o come in pairs, with a strange relationship between different kinds of g= eometric objects on the pairs. Since then, the subject has blossomed into= a vast field, with many different approaches and philosophies. I will gi= ve a brief introduction to the subject, and explain how one of these appr= oaches, developed with Bernd Siebert, has led to a general construction o= f mirror pairs.

Dan Abramovich will speak on

title: The Chow ring of a weighted blowup
abstract: This is mostly = a report on work of Brown PhD students Veronica Arena and Stephen Obinna.= The Chow groups of a blowup of a smooth variety along a smooth subvariet= y are described in Fulton's book using Grothendieck's "key formula", invo= lving the Chow groups of the blown up variety, the center of blowup, and = the Chern classes of its normal bundle. If interested in weighted blowups= , one expects everything to generalize directly. This is in hindsight cor= rect, except that at every turn there is an interesting and delightful su= rprise, shedding light on the original formulas for usual blowups, especi= ally when one wants to pin down the integral Chow ring of a stack theoret= ic weighted blowup. As an application, one obtains a quick derivation of = a formula, due to Di Lorenzo-Pernice-Vistoli and Inchiostro, of the Chow = ring of the moduli space $\overline{M}_{1,2}$ .

Title: The Library of Irish Mathematics

Abstract: The online Annals of Irish Mathemat= ics & Mathematicians documents over 5300 mathematical people who are/we= re Irish, work(ed) in Ireland, or had Irish doctoral advisors.

It also documents many hundreds of books writ= ten or edited by people in the first two categories, spanning 320 years. &n= bsp;The reach is broad, including mathematical physics, statistics,  a= nd more.

From geometry, number theory, algebra, real a= nd complex functions, DEs, fluid mechanics, relativity, and quantum theory,= to astronomy, actuarial maths, and maths education, it all adds up to a ve= ry impressive contribution.  

We will provide an overview of the wealth and= diversity of tomes to be found in this islandwide "virtual library of= Irish mathematics."

The evidence is very clear that Ireland has always punched well above its w= eight in this arena.

Flavour Puzzles and the LHCb experiment

Why is there no antimatter in the universe and why does nature provide us with three generations of similar fundamental fermions?  These so-called flavour puzzles are among the most intriguing mysteries in particle physics.  In the seminar we will discuss the origin of CP violation in the Standard Model and review highlights of CP violating measurements performed by the LHCb experiment. 

Finally, I will present recent results on the so-called flavour anomalies.

Title: Continuation with non-invasive control schemes

 

Abstract: Tracking unstable equilibria or periodic orbits in an experiment requires application of some type of stabilizing feedback control. This feedback control has to be non-invasive in the sense that its effect vanishes asymptotically. While in principle the most efficient way to achieve non-invasiveness is application of a (possibly simplified) Newton iteration, in practice many other approaches that are "naturally" non-invasive without requiring an iteration have been used. During work on controlling pedestrian flow simulations we discovered a generalisation of several commonly used techniques for non-invasively controlling equilibria that makes these techniques applicable to every generic scenario.

 

Best wishes,

Andrew Keane

For three decades I was a privileged academic professo= r - privileged to be employed in a job that allowed me to pursue a research= obsession from the very beginnings of an idea (as a junior professor), to = the point at the end of my career where the same idea has now become a powe= rful technology used in a variety of industrial applications. For 32 years = I followed a driving interest in a fascinating subject. Bit by bit I chippe= d away at the little corner of geophysics I had chosen. About a decade afte= r I started, I began to realize that the tantalizing seismic puzzle I was w= orking on (together with an incredibly talented group of students and postd= ocs) was possibly beginning to fall into place. After another decade the re= sults became impressive enough that the geophysical world began to notice. = Then, in the final decade of my career I saw the method widely adopted by o= thers. That was fun and fulfilling, and I want to share some of that with y= ou. This talk will be a visual and anecdotal retrospective of the progress = of that idea.

ABSTRACT OF LECTURE. For three decades I was a privileged academic professo= r - privileged to be employed in a job that allowed me to pursue a research= obsession from the very beginnings of an idea (as a junior professor), to = the point at the end of my career where the same idea has now become a powerful technology used in a variety= of industrial applications. For 32 years I followed a driving interest in = a fascinating subject. Bit by bit I chipped away at the little corner of ge= ophysics I had chosen. About a decade after I started, I began to realize that the tantalizing seismic puzzle I = was working on (together with an incredibly talented group of students and = postdocs) was possibly beginning to fall into place. After another decade t= he results became impressive enough that the geophysical world began to notice. Then, in the final decade of m= y career I saw the method widely adopted by others. That was fun and fulfil= ling, and I want to share some of that with you. This talk will be a visual= and anecdotal retrospective of the progress of that idea. Although The Seismic Inverse Problem sounds lik= e a topic of only passing interest to non-specialists, I will do what I can= to make this palatable for a general audience.

ABOUT THE SPEAKER. Gerhard Pratt worked as a professional engineer in the O= il & Gas industry before the start of his academic career. He obtained = an MSc and PhD from Imperial College (London, UK) in the late 1980s, he was= a post-doctoral fellow at the University of Toronto, and he was then a professor in three Earth Science Departments= : At Imperial College from 1992 until 1998, at Queen's University (Kingston= , Canada) until 2008, and finally at Western University (London, Canada) un= til 2021. He is now retired and living in Kingston, Ontario. He is currently appointed as an Adjunct Resea= rch Professor at both Western and Queen's. Gerhard Pratt has been actively = researching new methods in seismic wave modelling and imaging. He and his s= tudents have developed a number of innovations in these areas that make possible large scale forward and i= nverse modelling of exploration seismic data through numerical simulation o= f the full wave equation. Together they have been able to use these methods= in imaging structures in a wide range of applications, from small scale site investigations to wide angle = crustal seismology.

The speaker Gerhard Pratt and his collaborator Laurent Sirgue are recognized for their development of Full-Waveform-In= version with the Virgil Kauffman Gold Medal Award 2016 by the Society of Exploration Geophysists (SEG):

Time: 3:00PM

Location: E0.32 (beside Pi restaurant)

Abstract: We report on several elliptic differential inequalities featuring convolution terms. Such problems are motivated by the so-called Choquard equation arising in various fields, ranging from quantum physics to Newtonian relativity. The differential operator is given by the p-Laplace, mean curvature or the iterated Laplace operator. We provide optimal conditions in terms of the parameters for the existence of a positive solution.

This talk is based on a number of results jointly obtained with P. Karageorgis (Dublin), G. Singh (Dublin), Z. Yu (Dublin), Y. Miyamoto (Tokyo) and V. Moroz (Swansea).

Boole showed how to use = mathematics to give a rigorous account of logic, and how to use symbolic op= erations on binary digits to solve logical problems in a systematic manner.= Today, computers perform symbolic calculations at incredible speed, solvin= g problems in areas far beyond logic, of much greater complexity than Boole= can have envisioned. It is natural, then, to ask how we can hope to unders= tand and explain what programs do, without the desire or ability to look in= side the hardware and watch the binary digits fly by. The answer is again t= o use mathematics, taking a leaf from Boole=92s book. In this talk we discu= ss the main ideas behind mathematical (denotational) semantics, a framework= introduced by Dana Scott and Christopher Strachey for explaining program b= ehaviour in an abstract manner, independent of hardware details. We focus o= n the key principles underpinning this approach, referential transparency, = and compositionality, and why they are important. We finish with some comme= nts on the challenges of coping with modern multi-processors that exploit p= arallel evaluation to achieve great efficiency, while making it much harder= to understand program behaviour abstractly. ABOUT THE SPEAKER. Stephen Brookes is well known internationally for his seminal contributions= to semantics for concurrent programs and logics for reasoning about progra= m behaviour. He earned both his bachelor=92s degree in Mathematics and his= Ph. D. in Computer Science at Oxford University, joined Carnegie Mellon Un= iversity as a research computer scientist in 1981, and has been a full prof= essor there since 2006. His doctoral dissertation, supervised by Tony Hoar= e, was titled =93A Model for Communicating Sequential Processes=94. His wo= rk with Bill Roscoe led to the development of the failures-divergences mode= l of CSP. Over the years Brookes has developed a trace-based framework for= giving semantics to a range of parallel paradigms, including shared-memory= , synchronous and asynchronous communication. His work on Parallel Algol s= hows how these ideas can be extended to deal with a language that combines = concurrency with higher-order procedures. A long-term aim of his research has been to improve the design and analysis= of correct concurrent programs. His recent work on Concurrent Separation = Logic, in collaboration with Peter O=92Hearn, is a major development in thi= s direction.

George Boole is renowned as the inventor of what became Boolean logic,= now the fundamental basis of modern digital computing. Boole showed how to= use mathematics to give a rigorous account of logic, and how to use symbolic operations on binary digits to solve log= ical problems in a systematic manner. Today, computers perform symbolic cal= culations at incredible speed, solving problems in areas far beyond logic, = of much greater complexity than Boole can have envisioned. It is natural, then, to ask how we can hope to = understand and explain what programs do, without the desire or ability to l= ook inside the hardware and watch the binary digits fly by. The answer is a= gain to use mathematics, taking a leaf from Boole=92s book. In this talk we discuss the main ideas behind = mathematical (denotational) semantics, a framework introduced by Dana Scott= and Christopher Strachey for explaining program behaviour in an abstract m= anner, independent of hardware details. We focus on the key principles underpinning this approach, referential tra= nsparency, and compositionality, and why they are important. We finish with= some comments on the challenges of coping with modern multi-processors tha= t exploit parallel evaluation to achieve great efficiency, while making it much harder to understand progra= m behaviour abstractly.

 

ABOUT THE SPEAKER. 

Stephen Brookes is well known internationa= lly for his seminal contributions to semantics for concurrent programs and = logics for reasoning about program behaviour.  He earned both his bach= elor=92s degree in Mathematics and his Ph. D. in Computer Science at Oxford University, joined Carnegie Mellon Univer= sity as a research computer scientist in 1981, and has been a full professo= r there since 2006.  His doctoral dissertation, supervised by Tony Hoa= re, was titled =93A Model for Communicating Sequential Processes=94.  His work with Bill Roscoe led to the develo= pment of the failures-divergences model of CSP.  Over the years Brooke= s has developed a trace-based framework for giving semantics to a range of = parallel paradigms, including shared-memory, synchronous and asynchronous communication.  His work on Parallel Alg= ol shows how these ideas can be extended to deal with a language that combi= nes concurrency with higher-order procedures.

 

A long-term aim of his research has been t= o improve the design and analysis of correct concurrent programs.  His= recent work on Concurrent Separation Logic, in collaboration with Peter O= =92Hearn, is a major development in this direction. CSL supports correctness proofs for software that involves pointer manipul= ation and shared-memory concurrency, both notoriously difficult to get righ= t.  This work has had significant impact in both theory and in practic= e. Brookes and O=92Hearn were awarded the 2016 G=F6del Prize, given j= ointly by European Association for Theoretical Computer Science (EATCS) and= the Association for Computing Machinery Special Interest Group on Algorith= ms and Computational Theory (ACM SIGACT).   Currently, Brookes is working on truly concurrent semantic models for rela= xed memory concurrency.

Abstract: In a linear code, a nonzero codeword is said to be minimal if its=
 support does not contain the support of any other linearly independent cod=
eword. Minimal (linear) codes are linear codes whose nonzero codewords are =
all minimal. The study of these codes was motivated by their use for realiz=
ing secret sharing schemes.=C2=A0 From a combinatorial point of view, this =
results in studying codes such that the supports of the nonzero codewords a=
re a Sperner family, =C2=A0i.e. they form an antichain with respect to the =
inclusion.

In this talk, we analyze the geometric point of view of m= inimal linear codes. Using the well-known correspondence between equivalenc= e classes of $[n,k]_q$ codes over a finite field $\mathbb F_q$ and equivale= nce classes of $[n,k]_q$ projective systems in $\mathrm{PG}(k-1,q)$, we wil= l show that equivalence classes of $[n,k]_q$ minimal linear codes are in on= e-to-one correspondence with equivalence classes of strong blocking sets in= $\mathrm{PG}(k-1,q)$. These are collections of points whose intersection w= ith any hyperplane spans the hyperplane itself.

Motivated by coding= theory, many researchers focused on finding lower bounds on the length of = minimal codes of a given dimension over a given finite field or equivalentl= y on the size of strong blocking sets in a fixed finite projective space. F= urthermore, once a good lower bound is given, the natural question is to co= nstruct minimal codes or strong blocking sets whose length/size achieves th= e bound.

We will survey the known literature on the topic and presen= t related open questions.

The talk is based on a collection of works= made in collaboration with Martino Borello, Alessandro Neri and Alberto Ra= vagnani.

Title: Concordant geometries

Abstract: The `geometry' in the title refers = to Riemannian geometry, that is, the study of smooth manifolds equipped wit= h a Riemannian metric, with the choice of metric endowing the space with a = geometry. Equivalently, we can think of the shapes which can result when a manifold is embedded into Euclidean = space of suitably high dimension. We will be interested in geometries which= everywhere display positive curvature in one of a number of senses. On a g= iven manifold it makes sense to ask about diversity of such geometries. When considering this question, th= ere are certain natural ways in which we can view geometries as being equiv= alent, and this leads us to study the resulting equivalence classes. We wil= l explore some of these, focusing on the notion of `concordance', and describe some recent work with Boris B= otvinnik on this topic.

In three spatial dimensions this coupling as well as the self-interaction of the Φ field are both marginal on the tree-level. We compute the one-loop renormalization group equations treating the Φ field as well as the phonons on the same footing. We find that the velocities of the Φ field as well as of the phonons are renormalized yielding an effective dynamical exponent z > 1. The renormalization group flow is found to depend on the number of components N. Whereas we find run-away flow for N < 4 a new fixed-point emerges for N >= 4. We discuss the relation to known results for classical criticality. Our findings are directly relevant to insulating quantum critical antiferromagnets. --111151493-961750316-1696950145=:110009-- From owner-mathdep LISTSERV.HEANET.IE Wed Oct 18 10:32:35 2023 Return-Path: X-Spam-Checker-Version: SpamAssassin 3.4.0 (2014-02-07) on maths.ucd.ie X-Spam-Level: X-Spam-Status: No, score=0.2 required=5.0 tests=HEADER_FROM_DIFFERENT_DOMAINS, MAILING_LIST_MULTI,SPF_HELO_NONE,SPF_SOFTFAIL autolearn=no autolearn_force=no version=3.4.0 Date: Wed, 18 Oct 2023 10:31:55 +0100 Reply-To: grogers STP.DIAS.IE Sender: UCD Maths Department Distribution List From: George Rogers Subject: Maths: DIAS Lectures: Samhain agus Science - Oct-Nov 2023 To: MATHDEP LISTSERV.HEANET.IE Precedence: list List-Help: , List-Unsubscribe: List-Subscribe: List-Owner: Dear Colleagues, Now in its sixth year, Samhain agus Science brings together researchers from DIAS and around the world for a series of free in-person events that take inspiration from the Celtic festival of Samhain and look at the dark side of science.

Speaker: Richard Smith

Title: Well-posedness of the Geometric Thin-Film Equation


Date: Tue 24th October 2023

Time: 3:00PM

Location: E0.32 (beside Pi restaurant)

Abstract: The Geometric Thin-Film equation is a mathematical model of droplet spreading in the long-wave limit, which includes a regularization of the contact-line singularity. In a previous talk we showed that this equation has unique solutions that are $\frac{1}{2}$-H\'older continuous for all time $t \in \mathbb{R}^+$, and which can be expressed in terms of push-forwards of the initial positive Radon data $\mu \in \mathcal{M}(\mathbb{R})^+$.

In this talk we consider well-posedness of these solutions with respect to the $1$-Wasserstein (or Kantorovich-Rubinstein) distance on the set of Radon probability measures $\mathcal{P}_1(\mathbb{R})$ having finite first moment. We show that the above solutions can be ill-posed if the initial data contains atoms, but are well-posed when the initial data is atomless. Optimal transport theory plays a key role in the proof of the second result.

This is joint work with Lennon \'O N\'araigh and Khang Ee Pang (UCD).

Specifically, we wish to determine whether the gas is primordial, remaining from the bel= t's formation, or secondary, produced in-situ. Our research seeks to determ= ine the upper limit of the molecular hydrogen column density in the CO-rich= , edge-on exocometary belts around HD110058 and HD131488. We observed these disks using the advanced CRIRES+ = instrument on the VLT. We attempt to observe absorption from the 2.22-micro= n rovibrational absorption line of H2 via infrared spectroscopy. These data are complemented by exist= ing HST-STIS CO absorption data. By modeling the 2.22 micron line with the = IR spectral modeling tool RADIS, we can obtain an upper limit for the colum= n density of H2. This combined analysis will yield the first measurement of the H2/CO ratio in a CO-rich debris di= sk.

However, a first conjecture about the characterization of modular Nahm sums in terms of these elements (sometimes called "Nahm=E2=80= =99s Conjecture") turned out to be false. In this talk, I will discuss the motivation behind the conjecture and explain why it fails. Moreover, I will present a conditional direction of the conjecture: under certain conditions, the modularity of a Nahm sum implies the vanishing of all associated elements. *Further information:* https://maths.ucd.ie/~kazim_b/UCD_ANT_Seminar.html ------------------------------------------------------------- For other seminars in the Algebra and Number Theory series, see http://maths.ucd.ie/seminarseries/Algebra ------------------------------------------------------------- The following formats the above notice so as to be included in the mathdep google calendar title:: Modularity of Nahm sums content:: Matthias Storzer (Bonn) :: UCD Algebra and Number Theory seminar (http://maths.ucd.ie/seminarseries/Algebra) location:: Science East, Room 0.32 ("next to =CF=80") date-time:: Thu 26th Oct 2023 at 2:00PM --00000000000014d8bd060820464b Content-Type: text/html; charset="UTF-8" Content-Transfer-Encoding: quoted-printable

Abstract: The modularity properties of so-called Nahm sums are known=
 to be related to the vanishing of certain associated elements in the Bloch=
 group. However, a first conjecture about the characterization of modular N=
ahm sums in terms of these elements (sometimes called "Nahm=E2=80=99s =
Conjecture") turned out to be false. In this talk, I will discuss the =
motivation behind the conjecture and explain why it fails. Moreover, I will=
 present a conditional direction of the conjecture: under certain condition=
s, the modularity of a Nahm sum implies the vanishing of all associated ele=
ments.

Title: Estimating public and private contrace= ptive method supply shares at national and subnational administration level= s, using Bayesian hierarchical models

Abstract: Contraceptive method supply shares = reflect the contributions of the public and private sectors to the distribu= tion of a given method each year. Quantifying these public/private sector s= upply shares of contraceptive methods within countries is vital for effective and sustainable family planning de= livery. They are useful to Family Planning officials as they show where con= traceptive users have obtained their most recent supplies. Unfortunately, d= ue to the cost, many low- and middle-income countries (LMIC) are not in a position to carry out the national-scale sur= veys necessary to collect this data regularly. Therefore, they evaluate the= contraceptive supply market using out-of-date data.  

Using out-of-date supply share estimates for = family planning monitoring has significant knock-on effects. They may lead = to inaccurate conclusions on the stability of the contraceptive supply mark= et and not reflect the current trends within the contraceptive supply markets. In addition, the estimation of ot= her family planning indicators that depend on method supply shares will als= o be inaccurate and distorted. To date, neither Bayesian nor frequentist me= thods have been used to estimate this important family planning indicator.

In this talk, I propose a methodology using B= ayesian hierarchical penalised spline models for estimating modern contrace= ptive method supply shares, at national and subnational administration leve= ls, for LMICs participating in the global Family Planning 2030 initiative. I describe a series of Bayesian mo= dels that evaluate method supply shares using both large multi-country data= sets and computationally efficient single-country data sets. Lastly, using= case study countries, I evaluate the impact of using national-level annual contraceptive method supply shar= es with uncertainty to calculate another key family planning indicator, est= imated modern use.

Title: Properties of Abel universal functions II: boundary behaviour


Date: Tue 31st October 2023

Time: 3:00PM

Location: E0.32 (beside Pi restaurant)

Abstract: A holomorphic function on the unit disc $\mathbb{D}$ is called Abel universal if the family of its dilates is dense in the space of continuous functions on K, for any proper compact subset K of the unit circle. It has been recently shown that the class of Abel universal functions is residual in the space of holomorphic functions on $\mathbb{D}$. In this talk, I will discuss a wide range of boundary properties of Abel universal functions such as local growth, existence of Picard points and asymptotic values. Moreover, I will make comparisons with other well-known classes of holomorphic functions. (Joint work with St\'ephane Charpentier and Myrto Manolaki)

The prime example is the Kalb–Ramond B-field of string theory, which is found also in the low-energy supergravity limits. Mathematically, these gauge potentials are connections on higher or categorified principal bundles also known as gerbes. In the Abelian case, the theory of gerbes is well-established and used in many contexts. In this seminar, I will talk about how one can extend this theory to the non-Abelian setting. There, the situation is much more subtle. Although the topological construction of non-Abelian gerbes is relatively straightforward, defining a connection on such a gerbe requires much more work. After formulating the general construction, I will illustrate it by lifting the principal bundle corresponding to an instanton--anti-instanton pair to a string 2-group bundle.

The prime example is the Kalb–Ramond B-field of string theory, which is found also in the low-energy supergravity limits. Mathematically, these gauge potentials are connections on higher or categorified principal bundles also known as gerbes. In the Abelian case, the theory of gerbes is well-established and used in many contexts. In this seminar, I will talk about how one can extend this theory to the non-Abelian setting. There, the situation is much more subtle. Although the topological construction of non-Abelian gerbes is relatively straightforward, defining a connection on such a gerbe requires much more work. After formulating the general construction, I will illustrate it by lifting the principal bundle corresponding to an instanton--anti-instanton pair to a string 2-group bundle. Such ​"string structures'' are believed to play a role in the dynamics of M5-branes."

Title: The mirror model with = weight n^#loops - breaking translation invariance for large = n 


Date: Wed 1st November 2023

Time: = 3:00PM 

Location: E0.32 (beside Pi = restaurant) 

Abstract: Consider the Lorentz mirror model on = the 2d lattice: at each lattice site, independently place a mirror at 45 = degrees to the lattice with some probability p. The orientation of the = mirror is chosen independently, say north-west with probability = 0<q<1. Loops can then be formed which bounce off the mirrors, or = pass straight through lattice sites with no mirror. What is the = probability that the loop through some given edge is infinite? For p=3D1 = it is zero, but for 0<p<1 the problem is open. 

We study this model where we re-weigh = the measure by n^#loops, n>0. We discuss a form of breaking of = translation invariance, where for n large, the almost all the loops are = trivial loops surrounding black faces, or trivial loops surrounding the = white faces. We can see that the method applied also works for a model = of loops coming from a 1D quantum spin system, where the breaking of = translation invariance is known as dimerisation.

Title: Cooperation and competition in the cancer microenvironment shapes the emergence of drug resistance

 

Abstract: The environment in which the tumour lives is known to modulate drug resistance, offering protective and survival cues to cancer cells. However, cancer and non-cancer cells also must compete for shared resources such as space and nutrient. The resulting dynamics of complex interactions between the cancer cells, the host tissue, and the drug can be explored using a mathematical and computational framework which integrates experimental observations. In this talk I will use a range of modelling approaches that can explicitly capture the spatio-temporal dynamics of tumour growth, invasion and resistance observed clinically and experimentally. Elucidating the contributions of the tumour microenvironment in regulating treatment response, these models can offer insight into therapeutic strategies that can successfully control the emergence of drug resistance.

 

Best wishes,

Andrew Keane

Abstract: Consider a d-dimensional system of It=C3= =B4-type stochastic differential equations with m independent diffusio= ns where the drift and diffusion coefficients are not globally Lipschitz co= ntinuous but instead only locally Lipschitz and together satisfy a Khasmins= kii-type condition. It is known that both the explicit Euler-Maruyama and M= ilstein schemes fail to converge for such systems when applied over a unifo= rm mesh.

We construct an adaptive mesh that responds to the local behaviour of so= lutions by reducing the stepsize as solutions approach the boundary of a sp= here, invoking a convergent backstop method in the (rare) event that the ti= mestep becomes too small. With such a mesh, order-one strong <= span class=3D"gmail-mord">L2-convergence of the scheme ca= n be ensured, even when the diffusion coefficients of the SDE are non-commu= tative.

We examine how this adaptive strategy can be modified to allow for the d= iscretisation of systems of SDEs perturbed by a Poisson jump process indepe= ndent of the perturbing diffusion processes, without loss of order, as long= as the independent jump times can be pre-computed and included in the adap= tive mesh.

= Global structures of SQFTs from rank-one Seiberg-Witten geometries

Abstract: I will explore subtle aspects of rank-one 4d N=3D2 supersymmetric QFTs throu= gh their low-energy Coulomb-branch physics. This low-energy Lagrangian is f= amously encoded in the Seiberg-Witten (SW) curve, which is a one-parameter = family of elliptic curves. Less widely appreciated is the fact that various properties of the QFTs, including pro= perties that cannot be read off from the Lagrangian, are nonetheless encode= d into the SW curve, in particular in its Mordell-Weil group. This includes= the global form of the flavour group, the one-form symmetries under which defect lines are charged, and t= he "global form" of the theory. In particular, I will discuss in = detail the difference between the pure SU(2) and the pure SO(3) N=3D2 SYM t= heories from this perspective. I will also comment on 5d SCFTs compactified on a circle in this context.

All are welcome!

Our speaker is Minhyong Kim (Univ= ersity of Edinburgh), who will speak about: title: Diophantine Equations in Two Variables abstract: The search for integer or rational solutions of polynomials equat= ions in two variables has had a tendency to generate the most difficult pro= blems in mathematics for the last few thousand years, and surprisingly litt= le progress has been made. Nonetheless, this lecture will give a highly idi= osyncratic survey of what is known, concluding with the developments of the= last 20 years that make heavy use of homotopy theory.

It is our pleasure to invite you to this week= =92s Dublin Mathematics Colloquium (https://www.maths.tcd.ie/~dmc/) which t= akes places on Thursday November 2nd, 4pm in the Synge lecture theatre. Our= speaker is Minhyong Kim (University of Edinburgh), who will speak about:

title: Diophantine Equations in Two Variables=
abstract: The search for integer or rational = solutions of polynomials equations in two variables has had a tendency to g= enerate the most difficult problems in mathematics for the last few thousan= d years, and surprisingly little progress has been made. Nonetheless, this lecture will give a highly idiosyncratic = survey of what is known, concluding with the developments of the last 20 ye= ars that make heavy use of homotopy theory.


Best regards,
Marvin Anas Hahn and Florian Naef
