Cohomologie des G-faisceaux en caractéristique positive

Let G be a finite group, and X a noetherian G-scheme defined on an algebraically closed field k, whose characteristic divides the order of G. We define a refinement of the equivariant K-theory of X devoted to give a better account of the information related to modular representation theory. To cite this article: N. Borne, C. R. Acad. Sci.
