IAS Physics Group Meeting

Duality of Turbulence to a Solvable String Theory with Discrete Target Space
11:00am|Bloomberg Lecture Hall (IAS)

Abstract: The Navier–Stokes (NS) equations describe fluid dynamics through a high-dimensional, nonlinear partial differential equations (PDEs) system. Despite their fundamental importance, their behavior in turbulent regimes remains incompletely...

Mathematical Conversations

Visual Aspects of Gaussian Periods
6:00pm|Simons Hall Dilworth Room

Gaussian periods are certain sums of roots of unity.  Gauss introduced them in his work on straight edge and compass constructions of regular polygons.  Since then, Gaussian periods have played important roles in number theory and beyond.  It turns...

Special Year Seminar II

Surprising Representations in Cohomology of Configurations in Graphs
Nir Gadish
10:00am|Simonyi 101

Configuration spaces of points in graphs are nonsmooth analogs of braid arrangements, appearing in robotics applications and in theory of moduli spaces of tropical curves. While their cohomology is extremely difficult to understand, and depends on...

What is Tensor Isomorphism?
1:00pm|Simonyi Classroom (S-114)

Two graphs are isomorphic if they are the same up relabelling the vertices. Two matrices are equivalent if they are the same up to elementary row and column operations. Tensor isomorphism generalises these basic notions in graph theory and linear...

Joint PU/IAS Number Theory

Recent Progress on Gauss Sums and Primes
Alex Dunn
3:30pm|*Princeton University, Fine 214*

Large sieve inequalities are a fundamental tool used to investigate prime numbers and exponential sums. In this lecture I will explain my work that resolves a 1978 conjecture of S. Patterson (conditional on the Generalized Riemann hypothesis)...

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

Equivariant Cohomology and the (Symplectic) Diffeotype of Complexity-One Four-Manifolds
Tara Holm
9:15am|Remote Access

In this talk, we will explore the relationship between the geometry and topology of a complexity-one four-manifold and the combinatorial data that encode it. We will use a generators-and-relations description for the even part of the equivariant...

Princeton University Galread [Galactic/Extragalactic Reading Group]

TBA
11:00am|Zoom and Peyton Hall, Grand Central

Each week, we hold a relatively informal seminar/discussion series with an emphasis on extra-galactic and large-scale structure astrophysics.

During Galread a leader/visitor presents a recent paper to the discussion group. The PDF of the paper is...
