Tannaka-Krein duality for compact quantum homogeneous spaces. I. General theory
Kenny De Commer, Makoto Yamashita
An ergodic action of a compact quantum group G on an operator algebra A can be interpreted as a quantum homogeneous space for G. Such an action gives rise to the category of finite…

A construction of finite index C*-algebra inclusions from free actions of compact quantum groups
Kenny De Commer, Makoto Yamashita
Given an action of a compact quantum group on a unital C*-algebra, one can amplify the action with an adjoint representation of the quantum group on a finite dimensional matrix alg…
