Members' Colloquium

A (slightly less) brief look into the restricted 3-body problem
2:00pm|Simonyi Hall 101 and Remote Access

Despite the fact that the 3-body problem is an ancient conundrum that goes back to Newton, it is remarkably poorly understood, and is still a benchmark for modern developments. In this talk, I will give a (very) biased account of this classical...

Computer Science/Discrete Mathematics Seminar I

Locally testable codes with constant rate, distance, and locality, Part I
11:15am|Simonyi Hall 101 and Remote Access

A locally testable code (LTC) is an error correcting code that admits a very efficient membership test. The tester reads a constant number of (randomly - but not necessarily uniformly - chosen) bits from a given word and rejects words with...

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

Big fiber theorems and ideal-valued measures in symplectic topology
Yaniv Ganor
9:15am|Remote Access

In various areas of mathematics there exist "big fiber theorems", these are theorems of the following type: "For any map in a certain class, there exists a 'big' fiber", where the class of maps and the notion of size changes from case to case.

We...

The Unreasonable Effectiveness of Convexity in Symplectic Geometry
6:00pm|Birch Garden, Simons Hall

Convexity plays a central role in several geometric and dynamical problems in symplectic geometry. However, convexity is not preserved under structure preserving isomorphisms and it is unknown whether there exists an intrinsic property responsible...

Arithmetic Groups

Groups with bounded generation: properties and examples
11:00am|Remote Access
After surveying some important consequences of the property of bounded generation (BG) dealing with SS-rigidity, the congruence subgroup problem, etc., we will focus on examples of boundedly generated groups. We will prove that every unimodular $(n...

Seminar in Analysis and Geometry

The Shock Development Problem
2:00pm|Simonyi Hall 101 and Remote Access

A fundamental problem in the theory of compressible fluid is to provide a precise description of shock formation and development from smooth initial data. In this talk, I will present recent work in collaboration with Drivas, Shkoller and Vicol on...

Computer Science/Discrete Mathematics Seminar II

An Introduction to Determinantal Point Processes
10:30am|Simonyi Hall 101 and Remote Access

A random point process is said to be determinantal if finite subset probabilities correspond to principal minors of some matrix. Determinantal point processes (DPPs) appear in a wide variety of settings, from random matrix theory to combinatorics...
