Short course "Eisenstein Cohomology and Special Values of L-functions". Lecture 1: Eisenstein Kohomologie: A short introduction

Short course 1/3, online talk,

In this introductory lecture, I will start by setting up the context to study the cohomology of a locally symmetric space. Then I will discuss the notions of inner, cuspidal, and Eisenstein cohomology, and their mutual relationships. Whereas to a large extent I will work with a general connected reductive group over a number field, I will often specialize to GL(n) over a totally real or a totally imaginary number field.
