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 ...

A definition of relative discrete spectrum of noncommutative W*-dynamical systems is given in terms of the basic construction of von Neumann algebras, motivated from three perspectives: First, as a complementary concept ...

Relatively independent joinings ofW*-dynamical systems
are constructed. This is intimately related to subsystems of
W*-dynamical systems, and therefore we also study general properties
of subsystems, in particular fixed ...
