Computer Science/Discrete Mathematics Seminar I

Local Proofs with Arbitrarily Small Encoding Overhead
Noga Ron-Zewi
11:15am|Remote Access - see Zoom link below

The celebrated PCP theorem from the 90's shows that any mathematical proof can be encoded in such a way that its correctness can be verified locally by reading only a tiny number of bits from the encoding. This foundational result has had a...

Joint IAS/Princeton/Montreal/Paris/Tel-Aviv Symplectic Geometry Zoominar

Inverting primes in Weinstein geometry
Oleg Lazarev
9:15am|Remote Access

A classical construction in topology associates to a space $X$ and prime $p$, a new "localized" space $X_p$ whose homotopy and homology groups are obtained from those of $X$ by inverting $p$. In this talk, I will discuss a symplectic analog of this...

Mathematical Conversations

Many interacting quantum particles: open problems, and a new point of view on an old problem
Ian Jauslin
5:30pm|Remote Access

The main object of interest in this talk will be a system of many particles, modeled using the prescriptions of quantum mechanics. A significant challenge to studying such systems is that particles interact with each other, via weak or strong...

Geometric and Modular Representation Theory Seminar

Two Geometric Realizations of the Affine Hecke Algebra I
Pablo Boixeda Alvarez
3:00pm|Simonyi Hall 101 and Remote Access

In this talk we will begin the discussion of the results in Bezrukavnikov's "On Two Geometric Realizations of the Affine Hecke algebra". We will put all the previous tools described in this series of talks together to construct the equivalence of...

Stability and Testability

Constraint metric approximation and constraint stability
Liviu Paunescu
11:00am|Remote Access
Constraint metric approximation is about constructing an approximation of a group $G$, when the approximation is already given for a subgroup $H$. Similarly, constraint stability is about lifting a representation of a group $G$, when the lift is...

SL2 Seminar

A friendly introduction to microlocal sheaves
Michael McBreen
5:00pm|Remote Access

We will study the singularities of sheaves on a manifold via the symplectic geometry of its cotangent bundle, following the work of Sato, Kashiwara, Schapira and others. We will then see how to organise this information into a sheaf of categories...
