| Abstract: | A unital C∗-algebra A is weakly central if and only if for every x∈A there exists a sequence of elementary unital completely positive maps αn on A such that the sequence (αn(x)) converges to a central element. |
| Keywords: | C&lowast -algebra Elementary operator Dixmier approximation theorem |
