Special Year Seminar II

Twisted (co)homology of Matroids
10:00am|Simonyi 101 and Remote Access

The study of the topology of hyperplane arrangement complements has long been a central part of combinatorial algebraic geometry. I will talk about intersection pairings on the twisted (co)homology for a hyperplane arrangement complement, first...

Joint PU/IAS Number Theory

The Cohen-Lenstra Moments Over Function Fields
Aaron Landesman
3:30pm|314 Fine Hall

The Cohen-Lenstra heuristics are influential conjectures in arithmetic statistics from 1984 which predict the average number of p-torsion elements in class groups of quadratic fields, for p an odd prime. So far, this average number has only been...

Computer Science/Discrete Mathematics Seminar I

Quantum Locally Testable Codes and Codes with Transversal Gates
David (Ting-Chun) Lin
10:30am|Simonyi 101 and Remote Access

Recent advancements in quantum error correction have led to breakthroughs in good quantum low-density parity-check (qLDPC) codes, which offer asymptotically optimal code rates and distances. However, several open questions remain, including the...

Members' Colloquium

"Local-to-global" Theorems On High Dimensional Expanders
1:00pm|Simonyi 101 and Remote Access

Expansion in graphs is a well studied topic, with a wealth of applications in many areas of mathematics and the theory of computation.

High dimensional expansion is a generalization of expansion from graphs to higher dimensional objects, such as...

Joint IAS/PU Arithmetic Geometry

The Fargues-Fontaine de Rham stack
Juan Esteban Rodriguez Camargo
3:35pm|Simonyi 101 and Remote Access

The analytic de Rham stack is a new construction in Analytic Geometry whose theory of quasi-coherent sheaves encodes a notion of p-adic D-modules. It has the virtue that can be defined even under lack of differentials (eg. for perfectoid spaces or...

Computer Science/Discrete Mathematics Seminar II

Linear Stability of the Brunn-Minkowski Inequality
10:30am|Simonyi 101 and Remote Access

The Brunn-Minkowski inequality is a fundamental result in convex geometry controlling the volume of  the sum of subsets of $\mathbb{R}^n$. It asserts that for  sets $A,B\subset \mathbb{R}^n$ of equal volume and a parameter $t\in(0,1)$, we have $|tA+...

Symplectic Geometry Seminar

Anchored symplectic embeddings
Agniva Roy
1:00pm|Simonyi 101 and Remote Access

Symplectic manifolds exhibit curious behaviour at the interface of rigidity and flexibility. A non-squeezing phenomenon discovered by Gromov in the 1980s was the first manifestation of this. Since then, extensive research has been carried out into...
