Ergodicity and mixing of W*-dynamical systems in terms of joinings

Operator Algebras 2014-02-10 v3

Abstract

We study characterizations of ergodicity, weak mixing and strong mixing of W*-dynamical systems in terms of joinings and subsystems of such systems. Ergodic joinings and Ornstein's criterion for strong mixing are also discussed in this context.
