Actions of compact quantum groups on operator algebras. (English) Zbl 0960.58004

The author reports (without proofs) his recent results on actions of \(SU_q(2)\) quantum group on operator algebras. The mathematical structure is parallel to the boundary theory of random walks on discrete groups where a discrete group is replaced by the dual Hopf algebra of \(SU_q(2)\) and a random walk by the completely positive noncommutative Markov operator.
