Learning Seminar on Automorphic Forms

Introduction

Welcome to the Learning Seminar on Automorphic Forms. This seminar aims to provide an introduction to automorphic forms. We'll follow the books by Bump (Automorphic Forms and Representations) and Goldfeld (Automorphic Forms and L-Functions for the Group GL(n,R)) . We'll also have some guest lectures from other universities on more specialised topics like: Sieve methods for Automorphic forms and Hida Families.
