Let G be a finite group,we define higher K-theories K n (G) for G.In this setting,a finite group G is not treated as a groupoid Cas a category with the single object a and HomC(a; a) = G,but a finite category which re ects lots of information of G and its modular representation theory.The higher K-theories have nice properties with which we can deduce results for finite group theory and modular representation theory.
