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}…

Properly Outer Actions of Tensor Categories on C-algebras
Roberto Hernández Palomares, Miho Mukohara
We discuss proper outerness for finite index endomorphisms and finite index bimodules of simple C-algebras, extending recent similar results by Izumi concerning the purely infi…

Inclusions of simple C-algebras arising from compact group actions
Miho Mukohara
Inclusions of operator algebras have long been studied. In particular, inclusions arising from actions of compact groups on factors were studied by Izumi-Longo-Popa and others. The…
