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

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.
