SUMMARY:Analysis and/of PDE: On the Asymptotic Nature of First Order Mean
Field Games
DESCRIPTION:Francisco Silva, Université de Limoges\nIn this talk we consi
der a class of finite horizon first order mean field games. The main focus
here will be to provide a simple proof of convergence of symmetric N-play
er Nash equilibria in distributed open-loop strategies to solutions of the
mean field game in Lagrangian form. The talk is based on a joint work wit
h Markus Fischer (University of Padua).

SUMMARY:Applied mathematics seminar: Aggregation without attraction: Analy
sing collective dynamics of swimmers and tethered obstacles.
DESCRIPTION:Angelika Manhart, UCL\nAggregation phenomena in biology and be
yond are often attributed to attraction between individuals. In this work
we study how elastically tethered obstacles interacting with the swimmers
impact the macroscopically created patterns. Simulations of an individual-
based model reveal at least three distinct large-scale patterns: travellin
g bands, trails and moving clusters. This motivates the derivation of a ma
croscopic partial differential equations model, for which we assume large
tether stiffness. The result is a coupled system of non-linear, non-local
partial differential equations. We use linear stability analysis to predic
t pattern size from model parameters. Further analysis of the macroscopic
equations reveal that, surprisingly, the obstacle interactions induce shor
t-ranged swimmer aggregation, irrespective of whether obstacles and swimme
rs are attractive or repulsive.

SUMMARY:Maths HEP Lunchtime Seminars: Non-universality of hydrodynamics
DESCRIPTION:Akash Jain, University of Victoria\nThe late-time long-distanc
e behaviour of a many-body system is usually described by the framework of
hydrodynamics or similar condensed matter models based on the (possibly s
pontaneously broken) symmetries that the system enjoys. These models are c
haracterised by a set of transport coefficients, such as viscosities and c
onductivity, that capture the transport properties of conserved charges ov
er macroscopic scales. In this talk, we will investigate a new kind of tra
nsport coefficients that are not present in the usual formulation of hydro
dynamics, but nonetheless affect the late time dynamics of conserved charg
es. Physically, these new coefficients arise due to the interaction of the
hydrodynamic degrees of freedom with the background bath of thermal noise
present out of equilibrium. For the purposes of this investigation, I wil
l spend some time to review the newly developed Schwinger-Keldysh effectiv
e action formulation of non-equilibrium field theories, which allows one t
o systematically keep track of thermal noise and their correlations. The t
alk will be based on the recent preprint https://arxiv.org/abs/2009.01356.

SUMMARY:Probability Seminar: Roots of random polynomials near the unit cir
cle
DESCRIPTION:Marcus Michelen, University of Illinois\nIt is a well-known (b
ut perhaps surprising) fact that a polynomial with independent random coef
ficients has most of its roots very close to the unit circle. Using a pro
babilistic perspective, we understand the behavior of roots of random poly
nomials exceptionally close to the unit circle and prove several limit the
orems; these results resolve several conjectures of Shepp and Vanderbei.
We will also discuss how our techniques provide a heuristic, probabilistic
explanation for why random polynomials tend to have most roots near the u
nit circle. Based on joint work with Julian Sahasrabudhe.

SUMMARY:Geometry and Topology Seminar: Diffeomorphisms of solid tori
DESCRIPTION:Mauricio Bustamante, University of Cambridge\nThe homotopy gro
ups of the diffeomorphism group of a high dimensional manifold with infini
te fundamental group can be infinitely generated. The simplest example of
this sort is the solid torus $T=S^1\times D^{d-1}$. In fact, using Hatcher
, Igusa, and Waldhausen's approach to pseudoisotopy theory, it is possible
to show that in the range of degrees up to (roughly) $d/3$, the homotopy
groups of $Diff(T)$ contain infinitely generated torsion subgroups.\n\nIn
this talk, I will discuss an alternative point of view to study $Diff(T)$
which does not invoke pseudoisotopy theory: when $d=2n$, we interpret $Dif
f(T)$ as the "difference" between diffeomorphisms and certain self-embeddi
ngs of the manifold $X_g$ which is the connected sum of $T$ with the g-fol
d connected sum of $S^n \times S^n$.\n\nWe will see how infinitely generat
ed torsion subgroups appear from this perspective, and that they can be fo
und even up to degrees $d/2$. This is ongoing joint work with O. Randal-Wi
lliams.

SUMMARY:Statistics Seminars: How can we make Objective Bayesian Model Comp
arisons in a subjective Bayes world?
DESCRIPTION:Ioannis Ntzoufras, Athens University of Economics and Business
\nIn this talk I will provide a review of prior distributions for objecti
ve Bayesian model comparisons. The general principles, criteria and tools/
mechanisms that can be used in order to ensure a sensible Bayesian model c
omparison/selection procedure under the absence of any prior information w
ill be presented and discussed. Focus will be given in the most popular mo
del selection case: the variable selection problem. Some recent contribut
ions in the area of objective priors on model space will be also discussed
. Hopefully, after this talk you will have some guidance how to work to bu
ild sensible priors for Bayesian model comparisons.\n\nThe talk is based o
n the published paper:\nConsonni G., Fouskakis D., Liseo B., and Ntzoufras
I. (2018). Prior Distributions for Objective Bayesian Analysis. Bayesian
Analysis, 13, 627–679.

SUMMARY:Analysis and/of PDE: Spectral flow for pair compatible equipartiti
ons (after B. Helffer and M. Persson Sundqvist)
DESCRIPTION:Bernard Helffer, Université de Nantes\nGiven a bounded open
set $\Omega$ in $ \mathbb R^2$ and a regular \npartition of $\Omega$ by $
k$ open sets $D_j$, and assume that:\n\n* This is an equipartition $\math
frak l_k:= \lambda(D_j)$(for all $j$) where $\lambda(D_j)$ is the ground s
tate energy of the Dirichlet realization of the Laplacian in $D_j$\n\n* I
t has the pair compatibility condition, i.e. for any pair of neighbors in
the partition $D_i,D_j$, there is a linear combination of the ground state
s in $D_i$ and $D_j$ which is an eigenfunction of the Dirichlet problem in
$\Inte(\overline{D_i\cup D_j})$.\n\nTypical examples are nodal partitions
and spectral minimal partitions.\nThe aim is to extend the indices and Di
richlet-to-Neumann like\noperators introduced by Berkolaiko--Cox--Marzuola
in the nodal case to this more general situation. Like in the analysis o
f minimal partitions, this will\ninvolve in particular the analysis of su
itable Aharonov-Bohm operators.\n

SUMMARY:Statistics Seminars: Can we make engineering decisions despite unc

DESCRIPTION:Michael Beer , Institute for Risk and Reliability, Leibniz Uni
versity, Hannover\nEngineering systems are key elements for the functional
ity of our economy and even of our daily life. Hence, they should provide
their service in a very reliable and robust manner. They involve advanced
technology to a large extent and are thus assets, which seek a thoughtful
and economic care and maintenance. In order to address these requirements,
we need a technology for a reliable but quick analysis that provides unam
biguous and illustrative decision-support for operators and authorities. S
imultaneously, our engineering systems are often quite complex so that a d
etailed modeling and analysis for reliability assessment and maintenance p
lanning is very demanding. In addition, uncertainties arising from the com
plexity and also from, sometimes even unknown, operational, environmental
and man-made excitations or hazards undermine the clarity of predictions a
bout the systems behavior and its reliability. This conflict leads us to t
he question on how to make quick and informed decisions despite uncertaint
y and complexity. The seminar will feature some ideas and methods that cou
ld be helpful to address this problem. Specifically, the challenge of main
tenance of an aircraft turbine at most reasonable economic and technical e
ffort is considered. The technical ingredients include systems modeling, r
eliability analysis, and resilience-based decision-making.\n\n

SUMMARY:Geometry and Topology Seminar: Enumerative geometry of secant vari

DESCRIPTION:Mara Ungureanu, Universität Freiburg\nFor a curve in projecti

studied objects in classical algebraic geometry. We shall review some of
their basic properties and reformulate this extrinsic geometry problem in
terms of objects intrinsic to the geometry of the abstract curve, namely
secant divisors to a given linear series. We consider in particular enume
rative formulas counting the number of points in the intersection of two s
uch secant varieties on a given curve and discuss their validity in terms
of transversality of intersection of subvarieties inside the symmetric pro
duct of the curve.
