On the classification of simple Z-stable C*-algebras with real rank zero and finite decomposition rank | | Wilhelm Winter
; | | Date: |
9 Feb 2005 | | Subject: | Operator Algebras; Functional Analysis; K-Theory and Homology MSC-class: 46L85; 46L35 | math.OA math.FA math.KT | | Abstract: | We show that, if A is a separable simple unital C*-algebra which absorbs the Jiang-Su algebra Z tensorially and which has real rank zero and finite decomposition rank, then A is tracially AF in the sense of Lin, without any restriction on the tracial state space. As a consequence, the Elliott conjecture is true for the class of C*-algebras as above which, additionally, satisfy the Universal Coefficients Theorem. In particular, such algebras are completely determined by their ordered K-theory. They are approximately homogeneous of topological dimension less than or equal to 3, approximately subhomogeneous of topological dimension at most 2 and their decomposition rank also is no greater than 2. | | Source: | arXiv, math.OA/0502181 | | Services: | Forum | Review | PDF | Favorites | |
