$\mathcal{W}$-absorbing actions of finite groups on the Razak-Jacelon algebra

Norio Nawata

We say that a countable discrete group action $\alpha$ on a C${}^{\ast }$-algebra $A$ is \textit{$\mathcal{W}$-absorbing} if there exist a C${}^{\ast }$-algebra $B$ and an action $\beta$ on $B$ such that $…
