DESCRIPTION:Title: <a href="https://researchseminars.org/talk/QGS/102/">Cl
 assical actions of quantum permutations</a>\nby Amaury Freslon (Universit
 é Paris-Saclay\, France) as part of Quantum Groups Seminar [QGS]\n\n\nAbs
 tract\nQuantum permutation groups can act non-trivially\, and even ergodic
 ally\, on finite spaces. This is\, in view of many quantum rigidity result
 s\, an exception and it is natural to wonder whether there are other class
 ical spaces on which quantum permutations can act. H. Huang constructed a 
 family of such spaces\, and we will show that these are the only possibili
 ties. This is a joint work with F. Taipe and S. Wang.\n
