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...

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+...

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...

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...

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...

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...

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...

Not All Lakes are Circular: When Recreational Math Meets Analysis
6:00pm|Birch Garden, Simons Hall

You are swimming at the center of a circular lake with a bear waiting on the shore. The bear, unable to swim, moves four times faster on land than you do in water, but once on land, you can outrun it. Can you escape?

This classic riddle has been...
