The characteristic square of a factor and the cocycle conjugacy of discrete group actions on factors
Publikováno v:
Inventiones Mathematicae. 132:331-380
This paper has three main purposes; ®rst, to associate to any separable factor M a canonical commuting exact square of groups called the characteristic square ofM; secondly, to formulate at least in a preliminary way, a methodology for approaching `

We announce in this article that i) to each approximately finite dimensional factor R of any type there corresponds canonically a group cohomological invariant, to be called the intrinsic invariant of R and denoted Θ(R), on which Aut(R) acts canonic

We investigate the structure of the C*-algebras 𝒪ρ constructed by Doplicher and Roberts from the intertwining operators between the tensor powers of a representation ρ of a compact group. We show that each Doplicher-Roberts algebra is isomorphic

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

We study group extensions Δ→Γ→Ω, where Γ acts on a C*-algebraA. Given a twisted covariant representation π,V of the pairA, Δ we construct 3-cocycles on Ω with values in the centre of the group generated byV(Δ). These 3-cocycles are obstru

The main purpose of this paper is to establish a covariant representation theory for coactions of locally compact groups on C ∗ {C^{\ast }} -algebras (including a notion of exterior equivalence), to show how these results extend the usual notions f

We introduce a notion of normality for a nested pair of (ergodic) discrete measured equivalence relations of type II1. Such pairs are characterized by a groupQwhich serves as a quotient for the pair, or by the ability to synthesize the larger relatio

If K is a countable amenable group acting freely and ergodically on a probability space (Γ, μ), and G is an arbitrary countable amenable group, we construct an injection of the space of unitary representations of G into the space of unitary 1-cocyl

The purpose of this paper is to provide a complete set of invariants, up to cocycle conjugacy, of the possible actions, a, of a discrete amenable group G on a semifinite injective von Neumann algebra Jt. In the case where Ji = L°° (X', ft), this am
