Invariant states and ergodic dynamical systems on W*-algebras
Published online by Cambridge University Press: 24 October 2008
Abstract
An amenable semigroup of positive linear unital mappings on a W*-algebra is considered. Two main questions are dealt with: the existence of a normal faithful state invariant with respect to this semigroup and the description of ergodicity conditions. An explicit form of the ergodic projection, useful in treating the ergodicity problems, is also derived.
