Strongly outer actions of certain torsion-free amenable groups on the Razak-Jacelon algebra

Norio Nawata

Let $C$ be the smallest class of countable discrete groups with the following properties: (i) $C$ contains the trivial group, (ii) $C$ is closed un…

$W$ -absorbing actions of finite groups on the Razak-Jacelon algebra

Norio Nawata

We say that a countable discrete group action $I^\pm$ on a C $^{*}$ -algebra $A$ is \textit{ $W$ -absorbing} if there exist a C $^{*}$ -algebra $B$ and an action $I^^{2}$ on $B$ such that…

Approximate representability of finite abelian group actions on the Razak-Jacelon algebra

Norio Nawata

Let $A$ be a simple separable nuclear monotracial C $^{*}$ -algebra, and let $I^\pm$ be an outer action of a finite abelian group $I^$ on $A$ . In this paper, we show that $Î±\otimes \math…
