Abstract

Alternative characterisations of nuclear dimension and decomposition rank in terms of finite dimensional subalgebras and approximate partitions of unity are given for C*-algebras with real rank zero. These characterisations aid the understanding of the two concepts, as well as the difference between them, and lead to elementary proofs of known, important results.
