Computer Science/Discrete Mathematics Seminar II

Non-malleable extractors for constant depth circuits, and affine functions
10:30am|S-101

Seeded and seedless non-malleable extractors are non-trivial generalizations of the more commonly studied seeded and seedless extractors. The original motivation for constructing such non-malleable extractors are from applications to cryptography...

Eigenvalue bounds on sums of random matrices
1:15pm|S-101

For certain applications of linear algebra, it is useful to understand the distribution of the largest eigenvalue of a finite sum of discrete random matrices. One of the useful tools in this area is the "Matrix Chernoff" bound which gives tight...

Computer Science/Discrete Mathematics Seminar I

The mathematics of natural algorithms
11:15am|S-101

I will review some of the recent techniques we've used in our study of natural algorithms. These include Dirichlet series for matrix products, mean-field approximations in opinion dynamics, graph sequence grammars, and tools for renormalizing...

Differential Privacy Symposium

9:30am
Time:9:30am-5:30pmLocation:Wolfensohn Hall

Differential privacy disentangles learning about a dataset as a whole from learning about an individual data contributor. Just now entering practice on a global scale, the...

Joint IAS/Princeton University Number Theory Seminar

Albanese of Picard modular surfaces, and rational points
Mladen Dimitrov
4:30pm|Fine 214, Princeton University

This is a report on a work in progress in collaboration with Dinakar Ramakrishnan. A celebrated result of Mazur states that open modular curves of large enough level do not have rational points. We study analogous questions for the Picard modular...

Analysis/Mathematical Physics Seminar

Strong ballistic transport for quasiperiodic Schrodinger operators and Lieb-Robinson bounds for XY spin chains
1:30pm|S-101

I will discuss some results and open questions related to transport properties of 1D quasiperiodic operators with absolutely continuous spectra, and their relations to integrable many-body systems. Most of the results will be based on https://arxiv...

Working Seminar on Representation Theory

$\mathbb C$-representation theory of $p$-adic groups through the glass of types
11:00am|S-101

It is well known that representations of open compact subgroups (called types) play a fundamental role in studying representations of $p$-adic groups. We give an overview of the theory (after Bernstein, Moy-Prasad, Bushnell-Kutzko) in connection...
