A Criterion for $\mathcal{Z}$-Stability with Applications to Crossed Products

Operator Algebras 2016-09-01 v2

Abstract

Building on an argument by Toms and Winter, we show that if AA is a simple, separable, unital, Z\mathcal{Z}-stable C*-algebra, then the crossed product of C(X,A)C(X,A) by an automorphism is also Z-stable, provided that the automorphism induces a minimal homeomorphism on XX. As a consequence, we observe that if AA is nuclear and purely infinite then the crossed product is a Kirchberg algebra.
