Joint IAS/PU Number Theory

Simultaneous Non-Vanishing of L-Functions at the Central Point
Alexandra Florea
3:30pm|Simonyi 101 and Remote Access

In this talk, I will focus on simultaneous non-vanishing results for Dirichlet L-functions at the central point 1/2. Specifically, I will describe non-vanishing results (conditional on GRH) for two L-functions associated to Dirichlet characters in...

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...

Members' Colloquium

Fundamental Groups of Algebraic Varieties and the Shafarevich Conjecture
1:30pm|Simonyi 101 and Remote Access

The fundamental group $\pi_1(X)$ is an important invariant of a complex algebraic variety X.  Despite its topological nature, it is closely connected to the geometry of many algebraic structures on X.  In this talk I want to discuss two elementary...

Joint IAS/PU Arithmetic Geometry

Affine Schubert Varieties Are Splinters
Robert Cass
3:30pm|Simonyi 101 and Remote Access

Schubert varieties are known to be Frobenius split in positive characteristic by the work of Mehta and Ramanathan. More recently, Bhatt showed that the full flag variety for $GL_n$ is a splinter by entirely different methods. In this talk, we will...
