“Tate cohomology and cohomologically trivial modules”
Abstract: A G-module M is said to be cohomologically trivial if for any subgroup H of G, all the Tate cohomology groups of H with coeeficients in M are zero. We first define Tate cohomology using complete resolutions and discuss the equivalent conditions for being cohomologically trivial stated in 8th section of the chapter VI of Brown’s book on Cohomology of Groups.
