DESCRIPTION:Title: <a href="https://researchseminars.org/talk/QGS/55/">Bra
 ided quantum symmetries of graph C*-algebras</a>\nby Suvrajit Bhattacharje
 e (Charles University\, Czech Republic) as part of Quantum Groups Seminar 
 [QGS]\n\n\nAbstract\nA braided compact quantum group (over T) is\, roughly
  speaking\, a “compact quantum group” object in the category of T-C*-a
 lgebras equipped with a twisted monoidal structure. In this talk\, we shal
 l explain the existence of a universal braided compact quantum group actin
 g 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 com
 pute this universal braided compact quantum group for the Cuntz algebra.\n
