Stability and Testability

Stability and Invariant Random Subgroups
Henry Bradford
11:00am|Remote Access
Determining whether or not a given finitely generated group is permutation stable is in general a difficult problem. In this talk we discuss work of Becker, Lubotzky and Thom which gives, in the case of amenable groups, a necessary and sufficient...

Geometric and Modular Representation Theory Seminar

The linkage principle and the tilting character formula via Smith-Treumann theory
3:00pm|Simonyi Hall 101 and Remote Access

The linkage principle says that the category of representations of a reductive group $G$ in positive characteristic decomposes into "blocks" controlled by the affine Weyl group. We will discuss the beautiful geometric proof of this result that Simon...

Joint IAS/Princeton University Number Theory Seminar

Ax-Lindemann-Weierstrass Theorem (ALW) for Fuchsian automorphic functions
Joel Nagloo
4:30pm|Remote Access

Over the last decades, following works around the Pila-Wilkie counting theorem in the context of o-minimality, there has been a surge in interest around functional transcendence results, in part due to their connection with special points...

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

Pseudo-rotations vs. rotations
Başak Gürel
9:15am|Remote Access

The talk will focus on the question of whether existing symplectic methods can distinguish pseudo-rotations from rotations (i.e., elements of Hamiltonian circle actions). For the projective plane, in many instances, but not always, the answer is...

Princeton University Astroplasmas Seminar

Violation of the zeroth law of turbulence in space plasmas.
Romain Meyrand
2:30pm|Virtual Meeting

The movement and thermalization of turbulent energy between scales in plasmas is both fundamentally interesting and important for a wide range of modelling applications. In strongly magnetized space plasmas, energy in electromagnetic fluctuations is...

Princeton University Galread [Galactic/Extragalactic Reading Group]

TBA
Ben Horowitz
11:00am|Virtual Meeting

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...
