Higher Representation Theory
2:00pm|Simonyi Hall 101 and Remote Access

New types of symmetries have been considered in algebra and algebraic geometry and a higher analog of representation theory has been developed to answer questions of classical representation theory. Geometric representation theory can be viewed as...

Computer Science/Discrete Mathematics Seminar I

Strong refutation of semi-random Boolean CSPs
11:15am|Remote Access - see Zoom link below

For a fixed integer k > 1, the Boolean k-XOR problem consists of a system of linear equations mod 2 with each equation involving exactly k variables. We give an algorithm to strongly refute *semi-random* instances of the Boolean k-XOR problem on n...

Workshop on Topology: Identifying Order in Complex Systems

Persistent matchmaking
Uli Bauer
2:00pm|Remote Access

In this talk, I will give an overview of some recent results motivated by the computation and applications of persistent homology, a theory that creates a bridge between the continuous world of topology and the discrete world of data, and assigns...

Ruth and Irving Adler Expository Lecture in Mathematics

From superconductors to Coulomb gases: crystallization questions
Sylvia Serfaty
2:00pm|Remote Access - see Zoom link below

The physicist Abrikosov predicted that in certain superconductors, one should observe triangular lattices of vortices, now called Abrikosov lattices.  When studying ground states of Coulomb gases, which is motivated by questions in approximation...

Joint IAS/Princeton/Montreal/Paris/Tel-Aviv Symplectic Geometry Zoominar

Periodic Floer homology and the large-scale geometry of Hofer's metric on the sphere
9:15am|Remote Access

The group of Hamiltonian diffeomorphisms of a symplectic manifold admits a remarkable bi-invariant metric, called Hofer’s metric. My talk will be about a recent joint work with Dan Cristofaro-Gardiner and Vincent Humilière resolving the following...

Joint IAS/Princeton University Number Theory Seminar

Monoidal Structures on GL(2)-Modules and Abstractly Automorphic Representations
Gal Dor
4:30pm|Remote Access

Consider the function field F of a smooth curve over $F_q$, with $q > 2$.

L-functions of automorphic representations of $GL(2)$ over $F$ are important objects for studying the arithmetic properties of the field $F$. Unfortunately, they can be...

Mathematical Conversations

Newton, Euler, Navier, and Green
5:30pm|Remote Access

We touch lightly on the background of four mathematicians over four centuries whose names are famous in mathematics with my personal emphasis on fluid dynamics.

Geometric and Modular Representation Theory Seminar

On two geometric realizations of the anti-spherical module
3:00pm|Simonyi Hall 101 and Remote Access

The anti-spherical modules over the affine Hecke algebras admit two different realizations: one realization is in terms of the space of Whittaker functions on the affine flag manifolds and the other realization, due to Kazhdan-Lusztig, is in terms...
