$R$ -linear unitary preservers of C $^{*}$ -algebras

Lu Cui, Wenming Wu, Wei Yuan

We study the structure of general $R$ -linear unitary preservers between unital C $^{*}$ -algebras. Representing any unital $R$ -linear unitary preserver in terms of th…

Single commutators in $C^{*}$ -algebras

Lu Cui, Minghui Ma

Let $A$ be a simple unital $C^{*}$ -algebra with real rank zero, nonempty tracial state space $T (A)$ , and strict comparison of projections. We prove that ev…
