Abstract

Let G be a finite group, S the subgroup category of G, and M a Mackey functor on G. For full subcategories G and H of S, we have the direct limit M_⁎(G) and the inverse limit M^⁎(H) of M. In this paper we study relation between the canonical homomorphisms ind:M_⁎(G)→M(G) and res:M(G)→M^⁎(H).
