|Topic:||On residues of Eisenstein series - through a cohomological lens|
|Affiliation:||University of Vienna|
|Date:||Thursday, October 12|
|Time/Room:||4:30pm - 5:30pm/Fine 214, Princeton University|
The cohomology of an arithmetic subgroup of a reductive algebraic group defined over a number field is closely related to the theory of automorphic forms. We discuss in which way residues of Eisenstein series contribute non-trivially to the subspace of square-integrable classes in these cohomology groups.
