$\mathcal Z$-stability and finite dimensional tracial boundaries

Operator Algebras 2015-08-26 v2

Abstract

We show that a simple separable unital nuclear nonelementary CC^*-algebra whose tracial state space has a compact extreme boundary with finite covering dimension admits uniformly tracially large order zero maps from matrix algebras into its central sequence algebra. As a consequence, strict comparison implies Z\Z-stability for these algebras.
