If A is a fixed abelian group with endomorphism ring E, then for any group G, Ž . Ž . let G\* s Hom G, A and for any E-module M, let M\* s Hom M, A . The E evaluation map : G ª G\*\* is defined in the usual way and G is A-reflexive if G is an isomorphism. This is strongly related to the question of
