Abundance of invariant and almost invariant pure states of C*-dynamical systems
Ola Bratteli, Akitaka Kishimoto, Derek W. Robinson
We show that invariant states of C*-dynamical systems can be approximated in the weak*-topology by invariant pure states, or almost invariant pure states, under various circumstanc…
