DESCRIPTION:Title: <a href="https://stable.researchseminars.org/talk/QGS/1
 /">Furstenberg boundary of a discrete quantum group</a>\nby Mehrdad Kalant
 ar (University of Houston\, USA) as part of Quantum Groups Seminar [QGS]\n
 \n\nAbstract\nThe notion of topological boundary actions has recently foun
 d striking applications in the study of operator algebras associated to di
 screte groups. We will discuss the analogue concept for discrete quantum g
 roups\, show that in this generalization there still always exists a maxim
 al boundary action - the so-called Furstenberg boundary. We discuss applic
 ations in problems of C*-simplicity and uniqueness of the Haar state of th
 e dual.\n\nThis is joint work with Pawel Kasprzak\, Adam Skalski and Rolan
 d Vergnioux.\n
