Mathematical Conversations

Discrete Random Surfaces
Amol Aggarwal
5:30pm|Remote Access

In this talk we discuss two models of a discrete random surface. The first is a Markov process, like a simple random walk, under which the surface is grown according to random updates. The second chooses the surface uniformly at random, after...

Geometric and Modular Representation Theory Seminar

Towards a modular "2 realizations" equivalence
Simon Riche
7:00am|Remote Access

I will report on a project joint with Roman Bezrukavnikov (and partly with Laura Rider) aiming at constructing a variant for positive-characteristic coefficients of the equivalence constructed by Bezrukavnikov in "On two geometric realizations of an...

Computer Science/Discrete Mathematics Seminar II

On Chen’s recent breakthrough on the Kannan-Lovasz-Simonovits conjecture and Bourgain's slicing problem - Part III
Ronen Eldan
10:30am|Simonyi Hall 101 and Remote Access - see Zoom link below

This is the final talk in a 3-part series whose goal is to give background as well as a self contained proof of Chen's recent breakthrough on the KLS conjecture and slicing problem. After becoming familiar with the construction of stochastic...

Analysis Seminar

Korevaar-Schoen energy revisited
Nicola Gigli
4:30pm|Remote Access

Korevaar and Schoen introduced, in a seminal paper in 1993, the notion of `Dirichlet energy’ for a map from a smooth Riemannian manifold to a metric space. They used such concept to extend to metric-valued maps the regularity theory by Eells-Sampson...

Workshop on Topology: Identifying Order in Complex Systems

Twisted topological tangles or: the knot theory of knitting
Elisabetta Matsumoto
2:00pm|Remote Access

The Picard group of the stable module category of a finite group plays a role in many parts of modular representation theory. It was calculated when the group is an abelian $p$-group, by pioneering work of Dade in the 1970's, and a classification...
