Abstract

Using the continuous decomposition, we classify strongly free actions of discrete amenable groups on strongly amenable subfactors of type IIIλ,0<λ<1_\lambda, 0 < \lambda < 1. Winsl{\o}w's fundamental homomorphism is a complete invariant. This removes the extra assumptions in the classification theorems of Loi and Winsl{\o}w and gives a complete classification up to cocycle conjugacy.
