Kirchberg X-algebras with real rank zero and intermediate cancellation
Abstract
A universal coefficient theorem is proved for C*-algebras over an arbitrary finite T0-space X which have vanishing boundary maps. Under bootstrap assumptions, this leads to a complete classification of unital/stable real-rank-zero Kirchberg X-algebras with intermediate cancellation. Range results are obtained for (unital) purely infinite graph C*-algebras with intermediate cancellation and Cuntz-Krieger algebras with intermediate cancellation. Permanence results for extensions of these classes follow.
