Crossed product splitting of intermediate operator algebras via 2-cocycles

Yuhei Suzuki

We investigate the C*-algebra inclusions $B \subset A ⋊_{r} Γ$ arising from inclusions $B \subset A$ of $Γ$ -C*-algebras. The main result shows that, when $B \subset A$ is…

Amenable actions on ill-behaved simple C*-algebras

Yuhei Suzuki

By combining Rørdam's construction and the author's previous construction, we provide the first examples of amenable actions of non-amenable groups on simple separable nuclear C*-a…
