Joint IAS/Princeton University Number Theory Seminar

On the canonical, fpqc and finite topologies: classical questions, new answers (and conversely)
Yves André
4:00pm|Remote Access

Up to a finite covering, a sequence of nested subvarieties of an affine algebraic variety just looks like a flag of vector spaces (Noether); understanding this « up to » is a primary motivation for a fine study of finite coverings.

The aim of this...

Mathematical Conversations

Math & Computation: some principles, anecdotes and questions
Avi Wigderson
5:30pm|Remote Access

I planned to give a different talk, about recent work I am excited about. But then Helmut asked me to instead talk of "Dreams of mathematics and computer science". And his wish is my command...

I'll describe, mainly through works of some great...

SL2 Seminar

Invariance and monodromy of microlocal sheaves
David Nadler
4:00pm|Remote Access

I'll review results and examples of the invariance and monodromy of microlocal sheaves under mutations of their support. Then I'll suggest some problems in geometric representation theory where we would like to apply such techniques.

Analysis Seminar

Mean curvature flow in high co-dimension
William Minicozzi
4:30pm|Remote Access

Mean curvature flow (MCF) is a geometric heat equation where a submanifold evolves to minimize its area. A central problem is to understand the singularities that form and what these imply for the flow. I will talk about joint work with Toby Colding...

Computer Science/Discrete Mathematics Seminar II

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

This is the second talk in a 3-lecture 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 (a video of the first lecture can be found here:

Marston Morse Lectures

On the Ising perceptron model
Nike Sun
3:00pm|Remote Access via Zoom videoconferencing (link below)

(This lecture will be self-contained.) In high dimensions, what does it look like when we take the intersection of a set of random half-spaces with either the sphere or the Hamming cube? This is one phrasing of the so-called perceptron problem...
