摘要:In this talk, I shall present two semigroups of completely positive unital self-adjoint maps on the von Neumann algebras of the free orthogonal quantum group and the free permutation quantum group, and show that these semigroups satisfy ultracontractivity and hypercontractivity estimates. I also give results regarding spectral gap and logarithmic Sobolev inequalities.
