Workshop on Representation Theory and Analysis on Locally Symmetric Spaces

Wave-front set of some representations of unipotent reduction of the group SO(2n+1)
Jean-Loup Waldspurger
2:30pm|Simonyi Hall 101

Abstract: Let G be a connected reductive group over a p-adic field F and let $\pi$ be an irreducible admissible representation of $G(\overline{F})$. Due to Harish-Chandra, there is a development of the character of $\pi$ near the origin and we can...

Computer Science/Discrete Mathematics Seminar I

Boolean function analysis: beyond the Boolean cube
11:00am|West Building Lecture Hall

Boolean function analysis traditionally studies Boolean functions on the Boolean cube, using Fourier analysis on the group Z_2^n. Other domains of interest include the biased Boolean cube, other abelian groups, and Gaussian space. In all cases, the...

Joint IAS/Princeton University Number Theory Seminar

Fontaine–Mazur conjecture in the residually reducible case
Lue Pan
4:30pm|Fine Hall 214, Princeton University

We prove the modularity of some two-dimensional residually reducible p-adic Galois representations over Q under certain hypothesis on the residual representation at p. To do this, we generalize Emerton's local-global compatibility result and devise...

Theoretical Machine Learning Seminar

Small-loss bounds for online learning with partial information
Thodoris Lykouris
12:15pm|White-Levy Room

We consider the problem of adversarial (non-stochastic) online learning with partial information feedback, where at each round, a decision maker selects an action from a finite set of alternatives. We develop a black-box approach for such problems...

Mathematical Conversations

Bad behavior
Lillian Pierce
6:00pm|Dilworth Room

What do you do with a person who behaves in the worst possible way at every point in time? Well, I don’t know. But if you ask instead about an operator that picks out the worst possible behavior of a function, we sometimes know how to control it. We...

Analysis Seminar

Local eigenvalue statistics of random band matrices
Tatyana Shcherbina
1:30pm|Simonyi Hall 101

Random band matrices (RBM) are natural intermediate models to study eigenvalue statistics and quantum propagation in disordered systems, since they interpolate between mean-field type Wigner matrices and random Schrodinger operators. In particular...
