Analysis and Mathematical Physics

Lyapunov Exponents and Mixing in DiPerna-Lions Flows
Elia Bruè
2:30pm|Simonyi Hall 101 and Remote Access

In 2003, Bressan proposed a conjecture on the mixing efficiency of incompressible flows, which remains open. This talk surveys progress toward resolving Bressan’s mixing conjecture and presents a new result confirming its asymptotic validity for...

IAS Amplitudes Group Meeting

Geometric Symmetries for Black Hole Tidal Love Numbers
John Staunton
2:30pm|Bloomberg Lecture Hall (IAS)

Abstract: We present a unified geometric perspective on the symmetries underlying the spin 0, 1, and 2 static perturbations around a Schwarzschild black hole. The symmetries are exact, each forming an SO(3,1) group. They can be formulated at the...

Princeton University Dark Cosmos Seminar

Freezing-in the Axiverse
Christipher Dessert
4:00pm|Jadwin Hall, Joe Henry Room

Abstract - The presence of light axions in the infrared is a generic feature of many ultraviolet (UV) scenarios, including string theory, with the number of such axions N naturally O(10-100). Even when these axions interact very weakly with the...

IAS/Princeton/Montreal/Paris/Tel-Aviv Symplectic Geometry Zoominar

Non-squeezing and other rigidity results in LCS geometry
Pranav Chakravarthy
9:15am|Remote Access

Locally conformally symplectic (LCS) manifolds are generalisations of symplectic manifolds where the 2-form is not closed but instead satisfies the identity dω = η ∧ ω for a closed 1-form η. The study of these manifolds is equivalent to that of...

Computer Science/Discrete Mathematics Seminar I

Disjoint Pairs in Set Systems and the Combinatorics of Low-Rank Matrices
Benjamin Sudakov
11:00am|Simonyi Hall 101 and Remote Access

In this talk, I will discuss the solution to several problems in two closely related settings: set families in 2^[n] with many disjoint pairs, and low-rank matrices with many zero entries.

Highlights include a resolution of an old question of Daykin...

IAS Phenomenology Lunch and Meet

Information Discussions on Phenomenology and New Theories beyond the Standard Model
12:30pm|Bloomberg Hall Biology Conference Room (1st Floor, Room 113)

This semester, we will be beginning a *very informal* get-together every Monday of people interested in/working on phenomenology and new theories beyond the standard model.  The idea is to discuss over lunch, perhaps meet up around 12.20, grab lunch...
