Seminar in Analysis and Geometry

$H^{1/2-}$ weak solutions of the 3D Euler equations
2:00pm|Simonyi Hall 101 and Remote Access

In this talk, I will discuss joint work with Tristan Buckmaster, Nader Masmoudi, and Vlad Vicol in which we construct non-conservative solutions to the Euler equations which belong to the regularity class $C^0_t H^{1/2-}_x$. The motivation for such...

Computer Science/Discrete Mathematics Seminar II

Derandomization and its connections throughout complexity theory
10:30am|Simonyi Hall 101 and Remote Access

This is the first talk in a three-part series presented together with Lijie Chen.

The series is intended to survey the fast-paced recent developments in the study of derandomization. We will present:

  1. A revised version of the classical hardness...

Joint IAS/Princeton University Symplectic Geometry Seminar

Computing disk potentials via multi-directional sft
Chris Woodward
4:00pm|Simonyi 101 and Remote Access

I will talk about ongoing work with S. Venugopalan on computing disk potentials (which are counts of holomorphic disks with boundary on a Lagrangian) via multi-directional neck stretching. The focus will be on examples.

Members' Colloquium

Morrey's conjecture
2:00pm|Simonyi Hall 101 and Remote Access

Morrey’s conjecture arose from a rather innocent looking question in 1952: is there a local condition characterizing "ellipticity” in the calculus of variations? Morrey was not able to answer the question, and indeed, it took 40 years until first...

Computer Science/Discrete Mathematics Seminar I

Random algebraic varieties and their applications to hardness of approximation
11:15am|Simonyi 101 and Remote Access

This talk will serve as an introduction to the random algebraic method. This method has its origins in the following problem: suppose the binomial random graph comes "close" to having some property of interest P, but fails to do so because of the...

On symplectic capacities and their blind spots
Ely Kerman
9:15am|Remote Access

In this talk I will discuss a joint project with Yuanpu Liang in which we establish several properties of the sequence of symplectic capacities defined by Gutt and Hutchings for star-shaped domains using $S^1$-equivariant symplectic homology. Among...

Joint IAS/Princeton University Number Theory Seminar

Local (\ell = p) Galois Deformation Rings
Ashwin Iyengar
4:30pm|Simonyi Hall 101 and Remote Access

I will present joint work with V. Paškūnas and G. Böckle concerning deformation rings for mod $p$ Galois representations of $p$-adic local fields. After giving a short introduction to the subject, I will explain our main result which says that...
