Abstract: Abstract: Inclusions of operator algebras have long been studied. In particular, inclusions arising from actions of discrete (quantum) groups on factors were studied by Izumi-Longo-Popa and others. The correspondence between intermediate subfactors and subgroups is called the Galois correspondence. Analogues for actions on C*-algebras have been studied by Izumi, Cameron-Smith, Peligrad, and others. In this talk, I will talk about inclusions arising from isometrically shift-absorbing actions of compact groups on simple C*-algebras.
