Abstract:

A braided compact quantum group (over \mathbb{T}) is, roughly speaking, a “compact quantum group” object in the category of \mathbb{T}-C*-algebras equipped with a twisted monoidal structure. In this talk, we shall explain the existence of a universal braided compact quantum group acting on a graph C*-algebra in the category mentioned above. Time permitting, we shall sketch the proof, constructing along the way a braided analogue of the free unitary quantum group. Finally, as an example, we shall compute this universal braided compact quantum group for the Cuntz algebra.
