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 result extends Cuntz's classical decomposition for the Cuntz algebras $\mathcal{O}…

Crossed product splitting of intermediate operator algebras via 2-cocycles
Yuhei Suzuki
We investigate the C*-algebra inclusions arising from inclusions of -C*-algebras. The main result shows that, when …

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*-…
