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...

Floer's Jungle: 35 years of Floer Theory
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...

SL2 Seminar

Perverse sheaves on Grassmannians via microlocal geometry
4:00pm|Remote Access

I will present a finite-dimensional quiver algebra whose representations are equivalent to the category of Schubert-constructible perverse sheaves on the Grassmannian $Gr(k,n)$. The functor inducing the equivalence is constructed by analyzing the...

Computer Science/Discrete Mathematics Seminar II

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

In the mid 80's, Bourgain asked the following question: Is there a universal constant $c>0$ such that every compact convex set $K$ in $R^n$, of unit volume, must contain a slice (namely, a set of the form $K \cap H$ for some affine hyperplane $H$)...

Analysis Seminar

From hyperbolic billiards to statistical physics
4:30pm|Remote Access

Consider a point particle flying freely on the torus and elastically bouncing back from the boundary of fixed smooth convex obstacles. This is the celebrated Sinai billiard, a rare example of a deterministic dynamical system where rigorous results...

Marston Morse Lectures

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

I will describe recent progress in determination of asymptotic behavior in random constraint satisfaction problems, including the independent set problem on random graphs, random regular NAE-SAT, and random SAT. The results include sharp phase...
