Members' Colloquium

Barcodes in Topology and Analysis
Egor Shelukhin
1:00pm|Simonyi 101 and Remote Access

Persistence modules and their associated barcodes were intensively studied since the early 2000s with a view towards applied mathematics. Recently they have also found numerous applications in pure mathematics. We will discuss a few examples from...

Computer Science/Discrete Mathematics Seminar II

Cosystolic Expansion
Irit Dveer Dinur
10:30am|Simonyi 101 and Remote Access

High dimensional expansion comes in two flavors: spectral, which relates to random walks;  and cosystolic, which relates to chains of linear maps. The later is a more mysterious notion, which turns out related to a variety of applications such as...

Symplectic Geometry Seminar

Compactness Problems in Counting Special Lagrangians and Fueter Sections
Saman Habibi Esfahani
1:00pm|Simonyi 101 and Remote Access

This talk is based on joint work with Yang Li. I will discuss the problem of counting special Lagrangians in Calabi-Yau 3-folds and Fueter sections to define new numerical and Floer-theoretic invariants. The key challenges are the non-compactness...

IAS Amplitudes Group Meeting

Rays, Residues and the Moduli Space of Polygons
Nick Early
2:30pm|Bloomberg Lecture Hall (IAS)

Abstract: We describe a (surprisingly) novel, uniform formula for all inverse propagators appearing in $tr(\phi^3)$ amplitudes which are dual to a basis of rays of the tropical Grassmannian $TropG(2,n)$.  Our formula manifests the standard kinematic...

IAS Physics Group Meeting

Modular-Invariant Random Matrix Theory and AdS3 Wormholes
Gabriele Di Ubaldo
11:00am|Bloomberg Lecture Hall (IAS)

Abstract: We develop a non-perturbative definition of RMT2: a generalization of random matrix theory that is compatible with the symmetries of two-dimensional conformal field theory. Given any random matrix ensemble, its n-point spectral...

Special Year Seminar I

KP Solitons, Tropical Curves, and Voronoi Cells
Yelena Mandelshtam
2:00pm|Simonyi 101

The Kadomtsev-Petviashvili (KP) Equation has deep connections to algebraic curves, with solutions constructed from Riemann theta functions in the style of Krichever. As a curve undergoes tropical degeneration, its theta function simplifies to a...
