Injectivity for algebras and categories with quantum symmetry
Abstract
We establish the existence of injective envelopes for unital Yetter–Drinfeld C∗-algebras, and a related class of bimodule categories over rigid C∗-tensor categories. This implies monoidal invariance for boundary actions of Drinfeld doubles of compact quantum groups.
