DESCRIPTION:David Kyed\nI will report on joint works with Julien Bichon\, 
 Sven Raum\, Matthias Valvekens and Stefaan Vaes\, revolving around the com
 putation of L^2-Betti numbers for universal quantum groups. Among our main
  results is the fact that the first L^2-Betti number of the duals of the f
 ree unitary quantum groups equals 1\, and that all other L^2-Betti numbers
  vanish. All objects mentioned in the abstract will be defined\, more or l
 ess rigorously\, during the talk.
