Abstract
Abstract. We complete classification of discrete abelian or finite group actions on injective type III1 factors up to cocycle conjugacy. We also give a proof for Connes ’ characterization of the Ker (mod) and Cnt(M) for an injective factor M of type III. §0 Introduction. The purpose of this paper is to give a proof of Connes ’ announcement on approx-imately inner automorphisms and centrally trivial automorphisms of an injective
