Number Theory Seminar - Spring 2023

Eigenvarieties and p-adic L-functions


Description
I organised a seminar at Columbia University on eigenvarieties and their role in the study of p-adic L-functions. The main reference is Bellaïche's book [Bel21]. The initial plan is to cover at least the first two parts of this textbook and some of the third part. Another reference is Bellaïche and Chevenier's work [BC09] on families of Galois representations.
