Analysis and Mathematical Physics

On Singular Points in the Supercooled Stefan Problem
Max Engelstein
2:30pm|Simonyi Hall 101 and Remote Access

The supercooled Stefan problem models how water, cooled below freezing, forms into ice. Experiments have shown that this process can exhibit nucleation (pieces of ice forming spontaneously) and that fractal-like patterns can emerge in the ice. This...

Princeton University Dark Cosmos Seminar

Low-Mass Galaxies as Probes of Dark Matter Physics
Niusha Ahvazi
4:00pm|Jadwin Hall, Joe Henry Room

Abstract: Dwarf galaxies, despite (or perhaps because of) their small masses, are puzzles that challenge prevailing cosmological models. As the most common galaxies in the universe, they offer a powerful window into studying dark matter on the...

Special Year Learning Seminar

On a Problem of Polya and Some of its Evolutions
Umberto Zannier
2:00pm|Simonyi 101

Around 1921 Polya asked about the algebraicity of the indefinite integral of an algebraic function, in terms of the integrality of the coefficients in a power-series expansion. Polya nicely answered the special case of rational functions, using...

IAS Quantum Aspects of Black Holes Group Meeting

Averaging over N
Edward Witten
11:00am|Bloomberg Hall Physics Library

Abstract:  "Wormholes" seem to describe ensemble averages of some kind, but in realistic models of holography, like AdS_4xS^7, it seems there isn't anything to average over, except, in some examples, a single integer N. Is "averaging over N" enough...

Joint IAS/PU Number Theory

Local Intertwining Relation
Sug-Woo Shin
3:30pm|Simonyi 101 and Remote Access

The local intertwining relation (LIR) is an identity that gives precise information about the action of normalized intertwining operators on parabolically induced representations. It plays a central role in Arthur’s endoscopic classification for...

Princeton University Donald R. Hamilton Colloquium Series

The Search for Axion Dark Matter
Benjamin Safdi
4:00pm|Jadwin Hall A-10

Abstract: Axions are some of the best-motivated beyond the Standard Model particle candidates at present. These ultralight particles may account for the cosmological dark matter and explain other outstanding problems in nature, such as the strong-CP...
