Workshop on Topology: Identifying Order in Complex Systems

How to describe, analyze and interrogate dynamics of gene regulatory networks
Tomas Gedeon
2:00pm|Remote Access - see Zoom link below

We first describe mathematical foundation of DSGRN (Dynamic Signatures Generated by Regulatory Networks), an approach that provides a queryable description of global dynamics of a network over its entire param- eter space. We describe a connection...

Joint IAS/Princeton University Number Theory Seminar

On the locally analytic vectors of the completed cohomology of modular curves
Lue Pan
4:30pm|Remote Access

A classical result identifies holomorphic modular forms with highest weight vectors of certain representations of $SL_2(\mathbb{R})$. We study locally analytic vectors of the (p-adically) completed cohomology of modular curves and prove a p-adic...

Mathematical Conversations

The Mumford-Shah conjecture
Silvia Ghinassi
5:30pm|Remote Access

The Mumford-Shah functional has been introduced by Mumford and Shah in 1989 as a variational model for image reconstruction. Since then, it has been widely studied both from a theoretical and an applied point of view. In this talk we will focus on...

Geometric and Modular Representation Theory Seminar

(Equivariant) Cohomology of the affine Grassmannian and Ginzburg’s picture
3:00pm|Simonyi Hall 101 and Remote Access

This is the second talk in a series of three talks on the derived Satake. I will give an overview of an article by Ginzburg which laid the foundational ideas for this equivalence.

Stability and Testability

Stability and testability - a computational perspective
Jonathan Mosheiff
11:00am|Remote Access

In this talk we survey the recent connection (a joint work with Becker and Lubotzky) between certain group theoretic notions related to stability, and a novel class of problems from the realm of property testing. Consider the computational problem...

SL2 Seminar

Representations of GL_2(F_q) in defining characteristic: a number-theorist's perspective
Matthew Emerton
5:00pm|Remote Access

In this talk I hope to explain how the representation theory of $GL_n(F_q)$ (with q being a power of p) in char. p, and also in mixed characteristic $(0,p)$, plays an important role in the theory of Galois representations and the Langlands program...

Computer Science/Discrete Mathematics Seminar II

The threshold for the square of a Hamilton cycle
10:30am|Remote Access - see Zoom link below

We will talk about a recent result of Jeff Kahn, Bhargav Narayanan, and myself stating that the threshold for the random graph G(n,p) to contain the square of a Hamilton cycle is 1/sqrt n, resolving a conjecture of Kühn and Osthus from 2012. For...
