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...

Joint IAS/Princeton University Number Theory Seminar

Kolyvagin's conjecture and higher congruences of modular forms
Naomi Sweeting
4:30pm|Remote Access

Given an elliptic curve $E$, Kolyvagin used CM points on modular curves to construct a system of classes valued in the Galois cohomology of the torsion points of $E$. Under the conjecture that not all of these classes vanish, he gave a description...

Mathematical Conversations

Floer's Jungle: 35 years of Floer Theory
Siobhan Roberts and Helmut Hofer
5:30pm|Remote Access

An exceptionally gifted mathematician and an extremely complex person, Floer exhibited, as one friend put it, a “radical individuality.” He viewed the world around him with a singularly critical way of thinking and a quintessential disregard for...

Marston Morse Lectures

Probabilistic analysis of random CSPs
Nike Sun
3:00pm|Remote Access via Zoom videoconferencing (link below)

(This lecture is related to the preceding lecture, but I will try to make it self-contained as much as possible.) In this lecture I will elaborate on some of the existing mathematical approaches to the study of random CSPs, particularly involving...
