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 16eeca935ae57cd0445a2f233c3" title="Click to view the MathML source">ind:M⁎(G)→M(G) and e455b8d36" title="Click to view the MathML source">res:M(G)→M⁎(H).
