The standard construction for cocycle twisted and braided tensor product W $^{*}$ -algebras

K. De Commer, J. Krajczok

Given a locally compact quantum group $G$ and a (generalized) dual unitary $2$ -cocycle $I^^c ◯$ , any W $^{*}$ -algebra $A$ with a $G$ -action can be twisted into a new…

Amenable actions of compact and discrete quantum groups on von Neumann algebras

K. De Commer, J. De Ro

Let $G$ be a compact quantum group and $A \subseteq B$ an inclusion of $I ¨ $ -finite $G$ -dynamical von Neumann algebras. We prove that the $G$ -inclusion $A\…

Approximation properties for dynamical W*-correspondences

K. De Commer, J. De Ro

Let $G$ be a locally compact quantum group, and $A, B$ von Neumann algebras on which $G$ acts. We refer to these as $G$ -dynamical W $^{*}$ -algebras. We make…
