The Atiyah-Hirzebruch spectral sequence allows one to compute the A-cohomology groups of the space Xin terms of the A-cohomology groups of a point and the ordinary cohomology groups of the space X. SpletHDR(G)onH(G;R) is de ned so that the cohomology ring is an R(HDR(G))-module. In this paper we study the connection between the functor ‘cohomology of a nite group G’ and, for xed G, the action of HDR(G). A major problem is that derived equivalences are not well suited for restriction to subrings or quotient rings. techgymb3
