Abstract
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 point subsystems and compact
subsystems. This allows us to obtain characterizations of weak
mixing and relative ergodicity, as well as of certain compact subsystems,
in terms of joinings.
