Locally Symmetric Spaces Seminar

Semiclassical analysis, amplification, and subconvexity
Simon Marshall
1:45pm|Simonyi Hall 101

I will discuss an approach to the subconvexity problem for L-functions based on period integral formulae and amplification. In particular, I will describe work in progress with Ruixiang Zhang that attempts to prove a subconvex bound for the central...

Computer Science/Discrete Mathematics Seminar II

Operator Scaling via Geodesically Convex Optimization, Invariant Theory and Polynomial Identity Testing (Continued)
Yuanzhi Li
10:30am|Simonyi Hall 101

We propose a new second-order method for geodesically convex optimization on the natural hyperbolic metric over positive definite matrices. We apply it to solve the operator scaling problem in time polynomial in the input size and logarithmic in the...

Locally Symmetric Spaces Seminar

Concentration properties of automorphic forms and spherical varieties (continued)
10:00am|Dilworth Room

I will talk about some global questions on the concentration properties of automorphic forms that seem to be a natural environment in which to examine the interplay between the geometry and spectrum of spherical varieties, L-functions, and...

Members’ Seminar

The hidden landscape of localization
2:00pm|Simonyi Hall 101

Complexity of the geometry, randomness of the potential, and many other irregularities of the system can cause powerful, albeit quite different, manifestations of localization: a phenomenon of confinement of waves, or eigenfunctions, to a small...

Joint IAS/Princeton University Number Theory Seminar

Fourier-Jacobi cycles and derivative of L-functions
Yifeng Liu
4:30pm|Fine Hall 214, Princeton University

In this talk, we construct the so-called Fourier-Jacobi cycles on unitary Shimura varieties. The height pairing of these cycles can be regarded as the arithmetic analogue of classical Fourier-Jacobi periods for the pair of unitary groups of equal...

Synthetic homotopy theory: going beyond set-level mathematics
6:00pm|Dilworth Room

In addition to offering a formal system for doing ordinary (or "set-level") mathematics, Vladimir Voevodsky’s Univalent Foundations also suggest a new way of studying homotopy theory, called "synthetic homotopy theory".

I will show how synthetic...

The Weyl law for algebraic tori
Ian Petrow
4:45pm|Simonyi Hall 101

A basic but difficult question in the analytic theory of automorphic forms is: given a reductive group G and a representation r of its L-group, how many automorphic representations of bounded analytic conductor are there? In this talk I will present...
