Princeton University Gravity Initiative Spring Seminar Series

Phase Space of JT Gravity with Positive Cosmological Constant
Elba Alonso- Monsalve
12:30pm|Jadwin Hall, Princeton Gravity Initiative, 4th Floor

Abstract: We construct the classical phase space of Jackiw-Teitelboim (JT) gravity with positive cosmological constant on spatial slices with circle topology. We identify solutions not previously discussed in the literature, and find the phase space...

Members' Colloquium

Barcodes in Topology and Analysis
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...

Joint IAS/PU Arithmetic Geometry

Real groups, symmetric varieties, quantum groups and Langlands duality
3:35pm|Simonyi 101 and Remote Access

I will explain a connection between relative Langlands duality and geometric Langlands on real forms of the projective line (i.e. the real projective line or the twistor P1), then explain recent results using this to answer some questions in...

Computer Science/Discrete Mathematics Seminar II

Cosystolic Expansion
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...

Analysis and Mathematical Physics

The Smale Conjecture for $RP^3$ and Minimal Surfaces
Daniel Ketover
2:30pm|Simonyi Hall 101 and Remote Access

In the early 80s Hatcher proved the Smale Conjecture, asserting that the diffeomorphism group of the three-sphere retracts onto its isometry group.  The corresponding problem for $RP^3$ was open nearly 40 years, and resolved only in 2019 by a...
