Hilbert spaces attached to Möbius spaces (MINI TALK)
speaker: Georg Gruetznerabstract: In 2001, Y. Shalom asked if every hyperbolic group admits a uniformly bounded representation with a proper cocycle. In this talk we construct Sobolev spaces H(d) associated with a Möbius structure M. We show that M has a uniform Ahlfors-David constant, and use this observation to show that the norms on H(d) for different metrics d in the Möbius structure are comparable for a large class of functions. This is a partial result of a program to construct and study uniformly bounded representations for all hyperbolic groups
