Stabilization theorem and symmetric structure of Cuntz--Pimsner algebras

Miho Mukohara, Yuhei Suzuki

We establish a crossed product decomposition theorem for stabilized Cuntz--Pimsner algebras. This extends Cuntz's classical decomposition for Cuntz algebras and reveals an implicit…

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…

Amenable actions on finite simple C*-algebras arising from flows on Pimsner algebras

Yuhei Suzuki

Associated to a family of $G$ - $*$ -endomorphisms on a $G$ -C*-algebra $A$ satisfying certain minimality conditions, we give a $G$ -C*-correspondence $E$ over $A$ whose Cu…
