Special Year Research Seminar

Shape Invariant and Its Quantitative Applications
Jun Zhang
11:00am|Simonyi Hall 101

In this talk, we introduce a non-linear symplectic capacity for four-dimensional Euclidean domains $X$, known as the shape invariant of $X$, which encodes the embeddability of Lagrangian tori into $X$. We present a computational framework for this...

What is the Unique Games Conjecture?
1:00pm|Simonyi 101 and Remote Access

One of the problems in the OpenAI drop last month, the unique games conjecture has been a major problem in theoretical computer science, pertaining to PCPs and hardness of approximation. I will talk about the field, the background, and a little bit...

Princeton University Galread [Galactic/Extragalactic Reading Group]

TBA
2:00pm|Peyton Hall, Dome Room or Zoom

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...

Joint IAS/PU Number Theory

Euler Systems and Bloch—Kato for the Triple Product
Fernando Trejos Suarez
3:30pm|Simonyi 101

We discuss the construction of an Euler system for the triple product, the p-adic Galois representation $V = V_1 x V_2 x V_3$, where $V_1,V_2,V_3$ are the 2-dimensional representations attached to cuspforms $f_1,f_2,f_3$. Applications include new...

Princeton University PCTS Special Physics Talk

Ruling Out (Quantum) Memories
Chao Yin
4:30pm|407 Jadwin Hall, 4th Floor, PCTS Seminar Room

Abstract: Thermal quantum memories can preserve quantum information for exponentially long times simply by cooling the system. Such memories exist in three spatial dimensions, but the known construction relies on an iterative procedure, motivating...

Shuhao Li (Stony Brook): Topology of Lagrangians Via Open-Closed String Topology

The topology of Lagrangian submanifolds in the standard symplectic vector space $C^n$ is a fundamental yet poorly understood problem in symplectic topology. A related...
