Abstract: Consider a coaction of a locally compact group on a - algebra , and a closed normal subgroup of . We prove, following results of Echterhoff for abelian , that Mansfield's imprimitivity between and implements equivalences between Mansfield induction of representations from to and restriction of representations from to , and between restriction of representations from to and Green induction of representations from to . This allows us to deduce properties of Mansfield induction from the known theory of ordinary crossed products.
