摘要

我们考虑与分离图相关的泛C * -代数何时是精确的。具体地说，对于有限分离图，我们证明了泛C∗-代数是精确的当且仅当C∗-代数与图C∗-代数同构，而图C∗-代数恰好在分离图的泛C∗-代数同构时出现。

When universal separated graph $C^*$-algebras are exact

We consider when the universal C∗-algebras associated to separated graphs are exact. Specifically, for finite separated graphs we show that the universal C∗-algebra is exact if and only if the C∗-algebra is isomorphic to a graph C∗-algebra which occurs precisely when the universal and reduced C∗-algebras of the separated graph are isomorphic.
