Title: On a Generalisation of Tate Cohomology
Abstract:
Tate cohomology has been generalised from finite groups to all groups by several authors using different constructions. Therefore, a uniform theory is needed explaining why their approaches all lead to the same conclusions. The goal of the talk is to provide a rough sketch of such a uniform and general theory. After highlighting to which settings this theory applies, the talk concludes by stating two fundamental properties of the resulting generalisation of Tate cohomology.
