Abstrakt

We show that every nuclear O-stable -homomorphism with a separable exact domain has nuclear dimension at most 1. In particular separable, nuclear, O-stable C-algebras have nuclear dimension 1. We also characterise when O-stable C-algebras have finite decomposition rank in terms of quasidiagonality and primitive-ideal structure, and determine when full O2-stable -homomorphisms have nuclear dimension 0.
