We see the Poincaré series from a cohomological point of view and apply the idea to a finite group G acting on any commutative ring R with unity. For a 1cocycle c of G on the unit group R×, we define a |G|-torsion module Mc/Pc, which is independent of the choice of representatives of the cohomology class γ = [c]. We are mostly interested in determining Mc/Pc where G is the Galois group of a fin...
