Hausdorff School: "Arithmetic Groups, their Cohomology and Arithmetic Applications"

January 25 – January 29, 2016

Lipschitz Hall, Endenicher Allee 60

Organizers: Günter Harder, Christian Kaiser

Description: This school introduces into the field "Cohomology of Arithmetic Groups." We study cohomology groups of spaces, -which are constructed from arithmetic data-, with coefficients in sheaves, which also are of arithmetic origin. Hence the subject belongs to number theory.

The methods used to study these cohomology groups come from analysis, the theory of automorphic forms and related fields. Insights into the structure of these groups yield applications to number theory, for instance we get rationality results for special values of L-functions, and we will see how these special values have influence on the structure of the Galois group.
