Abstract: Suppose is a closed normal subgroup of a locally compact group . A coaction of on a -algebra can be inflated to a coaction of on , and the crossed product is then isomorphic to the induced -algebra Ind. We prove this and a natural generalization in which is replaced by a twisted crossed product ; in case is abelian, we recover a theorem of Olesen and Pedersen. We then use this to extend the Landstad duality of the first author to twisted crossed products, and give several applications. In particular, we prove that if
