IAS High Energy Theory Seminar

Aspects of Topological Symmetry, Holography, and Branes
Ibrahima Bah
11:00am|Bloomberg Lecture Hall (IAS) & Zoom

Abstract: In this talk I will discuss holographic duals of topological operators.  At low energy sugra, they can be realized by Page charge associated to Gauss law constraints. In the UV string theory, topological operators can be characterized by...

Analysis and Mathematical Physics

Renormalization, Diffusion Models, and Optimal Transport
Semon Kirillovich Rezchikov
2:30pm|Simonyi Hall 101 and Remote Access

I will explain how Polchinski’s formulation of the renormalization group of a statistical field theory can formally be seen as a gradient flow equation for a relative entropy functional. I will then discuss how this idea can be used to design...

Condensed Learning Seminar

Grothendieck-Riemann-Roch, Part I
Vadim Vologodsky
2:30pm|Princeton University, Fine Hall 314

Explain the formulation of the Grothendieck–Riemann–Roch theorem for analytic adic spaces: go through [And23, pp. 32-38] and define all relevant objects and maps. Before explaining the construction of the Chern class map, define the sheaf KU∧p on...

Computer Science/Discrete Mathematics Seminar I

Lower Bounds for Set-Multilinear Branching Programs
Shubhangi Saraf
11:00am|Simonyi 101 and Remote Access

In this talk, I will discuss lower bounds for a certain set-multilinear restriction of algebraic branching programs. The significance of the lower bound and the model is underscored by the recent work of Bhargav, Dwivedi, and Saxena (2023), which...

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...

Princeton University Gravity Initiative Seminar Series

Bubbles of AdS as Black Hole Mimickers
Suvendu Giri
12:30pm|Princeton University, Jadwin Hall, Princeton Gravity Initiative, 4th Floor

Abstract: I will present a case for the striking resemblance between bubbles of anti-de Sitter (AdS) within Minkowski spacetime and black holes. These solutions of Einstein’s equations are motivated by high-energy physics and lack horizons. We will...

Members' Colloquium

Triangulated Surfaces in Moduli Space
Sahana Vasudevan
2:00pm|Simonyi 101 and Remote Access

Triangulated surfaces are Riemann surfaces formed by gluing together equilateral triangles. They are also the Riemann surfaces defined over the algebraic numbers. Brooks, Makover, Mirzakhani and many others proved results about the geometric...
