Commutative ${C}^*$-subalgebras of simple stably finite ${C}^*$-algebras with real rank zero Ping NGWilhelm Winter 46L8546L35nuclear ${C}^*$-algebrasK-theoryclassification Let $X$ be a second countable, path connected, compact metric space and let $A$ be a unital separable simple nuclear $\mathcal{Z}$-stable real rank zero $C^{*}$-algebra. We classify all the unital $*$-embeddings (up to approximate unitary equivalence) of $C(X)$ into $A$. Specifically, we provide an existence and a uniqueness theorem for unital $*$-embeddings from $C(X)$ into $A$.
