DESCRIPTION:Title: <a href="https://researchseminars.org/talk/QGS/1/">Furs
 tenberg boundary of a discrete quantum group</a>\nby Mehrdad Kalantar (Uni
 versity of Houston\, USA) as part of Quantum Groups Seminar [QGS]\n\n\nAbs
 tract\nThe notion of topological boundary actions has recently found strik
 ing applications in the study of operator algebras associated to discrete 
 groups. We will discuss the analogue concept for discrete quantum groups\,
  show that in this generalization there still always exists a maximal boun
 dary action - the so-called Furstenberg boundary. We discuss applications 
 in problems of C*-simplicity and uniqueness of the Haar state of the dual.
 \n\nThis is joint work with Pawel Kasprzak\, Adam Skalski and Roland Vergn
 ioux.\n
