Homogeneity of the pure state space for the separable nuclear C ∗-algebras

Abstract

We prove that the pure state space is homogeneous under the action of the group of asymptotically inner automorphisms for all the separable simple nuclear C *-algebras. If simplicity is not assumed for the C *-algebras, the set of pure states whose GNS representations are faithful is homogeneous for the above action.
