Homogeneity of the pure state space of the Cuntz algebra
Ola Bratteli, Akitaka Kishimoto
We prove that the automorphism group of a Cuntz algebra of finite order acts transitively on the set of pure states which are invariant under some gauge actions (which may depend o…

Trace acaling automorphisms of certain stable AF algebras II
Ola Bratteli, Akitaka Kishimoto
Two automorphisms of a simple stable AF algebra with a finite dimensional lattice of lower semicontinuous traces are shown to be outer conjugate if they act in the same way on the…
