# Yifei Zhao - 15h30 - Drinfeld's construction of Hecke eigensheaf for GL_2.

Europe/Paris

Description

In 1982, Drinfeld constructed an automorphic form on GL_2 for every irreducible rank-2 local system on a curve over a finite field, satisfying the Hecke eigenproperty. His construction is purely geometric and launched what is today known as the geometric Langlands program. In this talk, I will review the early history of the geometric Langlands program and explain Drinfeld's original argument.
