The Least Prime with a Given Cycle Type
Robert Lemke Oliver
3:30pm|*Princeton University, Fine 214*

The Chebotarev density theorem is a powerful tool in number theory, in part because it guarantees the existence of primes whose Frobenius lies in a given conjugacy class in a fixed Galois extension of number fields.  However, for some applications...

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...

On the Distribution of Modular Points on Deformation Rings
John Bergdall
3:30pm|Simonyi 101 and Remote Access

The goal of this talk is to discuss a new local-global phenomenon in the Langlands program on automorphic forms and Galois representations. Spaces of modular forms are parametrized by weights, and those same weights parametrize local deformation...
