 >Projective representations of compact quantum groups and the quantum asse
 mbly map</a>\nby Ryszard Nest (Univ. Copenhagen) as part of Conference on 
 operator algebras and related topics in Istanbul\, 2021\n\n\nAbstract\nThe
  torsion phenomena play important role in the construction of the assembly
  map in the context of Baum-Connes conjecture. The corresponding case of q
 uantum groups is more involved\, since the torsion phenomena are not neces
 sarily associated to torsion subgroups.An important role in this context i
 s played by projective representations of quantum groups. We will describe
  the general structure of projective representations\, associated twisted 
 group C*-algebras and the related torsion phenomena for compact quantum gr
 oups.We will also describe the role that these results play in the context
  of the assembly map for compact quantum groups.This is ''work in progress
 '' joint with Kenny De Commer and Ruben Martos.\n
