Marston Morse Lectures

Connes Embedding Problem, Kirchberg's Conjecture and Tsirelson's Problem
Thomas Vidick
11:15am|Simonyi Hall 101 and Remote Access - see Zoom link below

The three problems referred to in the title originate in the theory of von Neumann algebras, C* algebras, and quantum information theory respectively. Each of them has been a deep long-standing open problem in its respective area. Surprisingly, the...

Probability Seminar

Topic #1 (Aru): A few recent stories about the Gaussian free field; Topic #2 (Ding): Long range order for three-dimensional random field Ising model
Juhan Aru and Jian Ding
10:15am|Simonyi 101 and Remote Access

Aru Abstract: In the first story we wonder about the ubiquity of the free field and look at a few characterisation theorems. In the second story we discuss the mutually benefiting relationship between the discrete free field and the O(N) spin model...

The Nonvanishing of Selmer Groups for Certain Symplectic Galois Representations
Samuel Mundy
4:30pm|Princeton University, Fine Hall 214

Given an automorphic representation \pi of SO(n,n+1) with certain nice properties at infinity, one can nowadays attach to \pi a p-adic Galois representation R of dimension 2n. The Bloch--Kato conjectures then predict in particular that if the L...

Wondering About Wandering Domains
Adi Glücksam
1:00pm|Simonyi Hall 101

The goal of this talk is to present two problems related to wandering domains. I will define the participating objects, and give a historical overview of what was done and what is left to do to solve these problems. 

No basic knowledge in complex...

Diffusion and Mixing for Two-dimensional Hamiltonian Flows
Michele Coti-Zelati
3:00pm|Simonyi Hall 101 and Remote Access

We consider general two-dimensional autonomous velocity fields and prove that their mixing and dissipation features are limited to algebraic rates. As an application, we consider a standard cellular flow on a periodic box, and explore potential...

Special Year Learning Seminar

Sets of Multiplicative Recurrence
10:30am|Simonyi 101 and Remote Access

Sets of recurrence were introduced by Furstenberg in the context of ergodic theory and have an equivalent combinatorial characterization as intersective sets, an observation which has led to interesting connections between these areas.

Originally...

Unbounded Fast Escaping Wandering Domains
Adi Glücksam
2:00pm|Simonyi 101 and Remote Access

Complex dynamics explores the evolution of points under iteration of functions of complex variables. In this talk I will introduce into the context of complex dynamics, a new approximation tool allowing us to construct new examples of entire...

Strong Bounds for 3-Progressions: In-Depth
Raghu Meka and Zander Kelley
10:30am|Simonyi Hall 101 and Remote Access

Suppose you have a set A of integers from {1, 2, …, N} that contains at least N / C elements.  Then for large enough N, must A contain three equally spaced numbers (i.e., a 3-term arithmetic progression)? 

In 1953, Roth showed that this is indeed...
