✦ Synopsis


We show that every (C^{})-algebra with real rank zero has exponential rank (\leqslant 1+\varepsilon). Consequently, (C^{})-algebras with real rank zero have the property weak (FU). We also show that if (A) is a (\sigma)-unital (C^{})-algebra with real rank zero, stable rank one, and trivial (K_{1})-group then its multiplier algebra has real rank zero. If (A) is a (\sigma)-unital stable (C^{})-algebra with stable rank one, we show that its multiplier algebra has real rank zero if and only if (A) has real rank zero and (K_{1}(A)=0).
