Representation and cohomologies of groups and semigroups
This article surveys results related to the cohomology of lattices over group rings, particularly over the group ring of the Klein four--group. It is shown that in this setting, syzygies coincide with the Auslander-Reiten translation, enabling the full computation of Tate cohomology for all lattices...
