Poisson boundary of the discrete quantum group A_u(F)^
We identify the Poisson boundary of the dual of the universal compact quantum group Au(F) with a measurable field of ITPFI (infinite tensor product of finite type I) factors.sponsorship: Department of Mathematics, K.U.Leuven, Belgiumstatus: Publishe
Identification of the Poisson and Martin boundaries of orthogonal discrete quantum groups
The Poisson and Martin boundaries for invariant random walks on the dual of the orthogonal quantum groups A_o(F), are identified with
higher dimensional Podles spheres that we describe in terms of generators and relations. This provides the first such identification for random
walks on non-amenable discrete quantum groups.status: Publishe
