Princeton University Galread [Galactic/Extragalactic Reading Group]

How Ram Pressure Drives Radial Gas Motions in the Surviving Disk
Stephanie Tonnesen
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...

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...

Institute for Advanced Study/Princeton University Early Universe/Cosmology Lunch Discussion

Large scale structure formation in theories with scale dependent linear growth
Alejandro Aviles
12:30pm|West Building Seminar

In this talk, I will present recent developments in perturbation theory regarding the study of the large-scale clustering of galaxies in theories with scale-dependent linear growth, such as those involving massive neutrinos and modified gravity. The...

Joint IAS/Princeton University Symplectic Geometry Seminar

A Coproduct Structure on Symplectic Cohomology
Lea Kenigsberg
4:00pm|Fine 314 and Remote Access

I will discuss coproduct structures and why we care about them. Then I will define a new coproduct structure on symplectic cohomology and indicate how to compute it in an example.

Joint PU/IAS Arithmetic Geometry

On the geometry of p-adic Shimura varieties
Mingjia Zhang
4:30pm|Simonyi Hall 101 and Remote Access

Shimura varieties play an important role in the Langlands program. In this talk I will explain a conjectural fiber product structure on them as p-adic adic spaces, which generalizes the fiber product formula of Mantovan. To understand the conjecture...

Computer Science/Discrete Mathematics Seminar II

The Lens of Abelian Embeddings
10:30am|Simonyi Hall 101 and Remote Access

A predicate $P:\Sigma^k \to {0,1}$ is said to be linearly embeddable if the set of assignments satisfying it can be embedded in an Abelian group. 

In this talk, we will present this notion and mention problems it relates to from various areas...

Special Year Research Seminar

On the Maximum of a Twisted Divisor Function
Dimitris Koukoulopoulos
2:00pm|Simonyi 101 and Remote Access

Given $n\in\mathbb{N}$ and $\xi\in\mathbb{R}$, let $\tau(n;\xi)=\sum_{d|n}d^{i\xi}$. Hall and Tenenbaum asked in their book \textit{Divisors} what is the value of $\max_{\xi\in[1,2]} |\tau(n;\xi)|$ for a ``typical'' integer $n$. I will present work...
