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
Daniel Juteau
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...
