β¦ Synopsis
We show that the Brauer map for the exterior tensor product of two G-algebras can be expressed as a tensor product of their Brauer maps. As a consequence, we prove that the tensor module of two connected modules for the group algebra is also connected and its defect group is the direct product of their defect groups. We also show that this process is compatible with the association deΓΏned by Barker (J.

We consider an algebraic D-module M on the a ne space, i.e. a system of linear partial di erential equations with polynomial coe cients. We give an algorithm for computing the cohomology groups of the restriction of M to a linear subvariety by using a free resolution of M adapted to the V -ΓΏltration
