SL2 Seminar

Automorphic gluing functor in Betti geometric Langlands
4:00pm|Remote Access

I'll discuss joint work with Zhiwei Yun constructing a natural functor from the automorphic category of a nodal curve to the automorphic category of a smoothing. The results depend on the microlocal geometry of sheaves with nilpotent singular...

Celebration of Women in Mathematics

Interview with Dr. Monica Vazirani
Monica Vazirani
1:00pm

Dr. Monica Vazirani is a professor at UC Davis.  She received her PhD from UC Berkeley in 1999, after which she had an NSF postdoc she spent at UC San Diego and UC Berkeley, as well as postdoctoral positions at MSRI and Caltech.  Dr. Vazirani's...

Geometric and Modular Representation Theory Seminar

Frobenius exact symmetric tensor categories
3:00pm|Simonyi Hall 101 and Remote Access

I will report on a joint work in progress with K. Coulembier and V. Ostrik. We show that a symmetric tensor category in characteristic $p > 0$ admits a fiber functor to the Verlinde category (semisimplification of $Rep(Z/p)$) if and only if it has...

Mathematical Conversations

Symmetries in symbolic dynamics
Bryna Kra
5:30pm|Remote Access

Originating in the work of Hadamard in the 1890’s on the coding of geodesic flow, symbolic dynamics has become a key tool for studying topological, smooth, and measurable dynamical systems. The automorphism group of a symbolic system capture its...

Quantum Groups Seminar

Kazhdan-Lusztig equivalence
4:00pm|Remote Access

The talk introduces the Kazhdan-Lusztig equivalence between the Kazhdan-Lusztig category of representations of affine algebra and category of modules over the quantum group.

Joint IAS/Princeton University Number Theory Seminar

Expansion and parity
4:30pm|Remote Access

I will discuss recent work with Harald Helfgott in which we establish roughly speaking that the graph connecting $n$ to $n \pm p$ with $p$ a prime dividing $n$ is almost "locally Ramanujan". As a result we obtain improvements of results of Tao and...

Analysis Seminar

Eigenfunction concentration via geodesic beams
4:30pm|Remote Access

A vast array of physical phenomena, ranging from the propagation of waves to the location of quantum particles, is dictated by the behavior of Laplace eigenfunctions. Because of this, it is crucial to understand how various measures of eigenfunction...
