Every countably infinite group is almost Ornstein

Abstract

We say that a countable discrete group $G$ is {\em almost Ornstein} if for every pair of standard non-two-atom probability spaces $(K,\kappa ),(L,\lambda )$ with the same Shannon entropy, the Bernoulli shifts $G \cc (K^G,κ^G)$ and $G \cc (L^G,λ^G)$ are isomorphic.
