A generalization of Smith theory. (English) Zbl 0635.57020
Let G be a finite p-group and let X be a finite dimensional G-CW-complex with finite dimensional mod p-cohomology. Let SX denote the subcomplex of singular points X and let $$FX:=X/SX$$. The author found some inequalities which involve dimensions of the mod p-cohomology groups of X, SX and FX/G. His inequalities are sharper than those which can be obtained from the classical P. A. Smith theory. The proofs are based on an interpretation of the (ordinary) cohomology groups of X, SX and FX/G as Bredon equivariant cohomology groups of X with coefficients in suitable systems.
