Evans-Kishimoto type argument for actions of discrete amenable groups on McDuff factors
arXiv:math/0505311
Abstract
We apply the Evans-Kishimoto type argument for centrally free actions of discrete amenable groups on McDuff factors, and classify them. Especially, we present a different proof that the Connes-Takesaki modules are complete cocycle conjugacy invariants for centrally free actions of discrete amenable groups on injective factors.
