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...

Joint IAS/PU Groups and Dynamics Seminar

Arithmetic on Markoff Surfaces
Daniel Martin
4:30pm|Simonyi 101

The generalized Markoff equation gives rise to a dynamical system via the Markoff group acting on the solution set. This talk considers the resulting dynamics over finite fields, which has strong connections with combinatorial group theory and...

Set Theory Group

The Ultrapower Axiom, Determinacy, and Very Large Cardinals.
Gabriel Goldberg
4:00pm|Simonyi Hall 101

Abstract. This talk will survey the Ultrapower Axiom (UA), an amalgamation principle in set theory that has emerged as a common structural feature of three very different set-theoretic frameworks: canonical inner models, determinacy axioms, and very...
