Joint IAS/Princeton University Number Theory Seminar

The Hasse-Weil zeta functions of the intersection cohomology of minimally compactified orthogonal Shimura varieties
Yihang Zhu
4:30pm|S-101

Initiated by Langlands, the problem of computing the Hasse-Weil zeta functions of Shimura varieties in terms of automorphic L-functions has received continual study. We will discuss how recent progress in various aspects of the field has allowed the...

Analysis/Mathematical Physics Seminar

Universality in numerical computations with random data. Analytical results.
Percy Deift
2:00pm|S-101

This is joint work with Tom Trogdon. Here the author shows how to prove universality rigorously for certain numerical algorithms of the type described in the first lecture. The proofs rely on recent state of the art results from random matrix theory...

Working Seminar on Representation Theory

Categorification of the positive half of $\mathbb{U}_q(\mathfrak{sl}_2)$
11:00am|S-101

We will talk about the categorification of the positive half of the quantum group $\mathbb{U}_q(\mathfrak{sl}_2)$ using the module categories over NilHecke algebras. We hope to explain the idea of categorification using this example.

Joint IAS/Princeton University Symplectic Geometry Seminar

From Lusternik-Schnirelmann theory to Conley conjecture
Başak Gürel
3:00pm|Fine 224, Princeton University

In this talk I will discuss a recent result showing that whenever a closed symplectic manifold admits a Hamiltonian diffeomorphism with finitely many simple periodic orbits, the manifold has a spherical homology class of degree two with positive...

Computer Science/Discrete Mathematics Seminar II

Real rooted polynomials and multivariate extensions
10:30am|S-101

I will introduce two notions that generalize the idea of real rootedness to multivariate polynomials: real stability and hyperbolicity. I will then show two applications of these types of polynomials that will (hopefully) be of interest to the CS...
