Stable rank for crossed products by finite group actions with the weak tracial Rokhlin property

Xiaochun Fang, Zhongli Wang

Let $A$ be an infinite-dimensional stably finite simple unital C*-algebra, let $G$ be a finite group, and let $\hat{I}\pm :G\to \mathrm{Aut}(A)$ be an action of $G$ on $A$ whi…
