Special Year Seminar I

The Moduli Space of Matroids
2:00pm|Simonyi 101 and Remote Access

Lecture Series Framework:  A unifying framework for F1-geometry, tropical schemes and matroid theory. In this series of 3 lectures, I will present a recent approach towards F1-geometry and its links to tropical geometry, matroid theory, Lorentzian...

Joint IAS/PU Groups and Dynamics Seminar

Furstenberg Entropy Spectrum of Stationary Actions
Tianyi Zheng
4:30pm|Simonyi 101

In this talk we will discuss some aspects of the question: given a group, what is the range of Furstenberg entropy of ergodic stationary actions of it? For the special linear group and its lattices, constraints on this spectrum come from Nevo-Zimmer...

Absolute Continuity of the Robin Harmonic Measure On Rough Domains
Guy David
2:30pm|Simonyi Hall 101 and Remote Access

The question of asbolute continuity, with respect to the reference measure, of the harmonic measure on a domain with rough boundary has been the object of many important results. Here we ask about the similar question, but where the Dirichlet...

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+...

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...

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...

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...
