摘要: By a result of Nagy, the C � -algebra continuous func- tions on q-deformation Gq simply connected semisimple com- pact Lie group G is KK-equivalent to C(G). We show that under this equivalence K-homology class Dirac operator Gq, which we constructed in an earlier paper, corresponds classi- cal operator. Along way prove for appropriate choice isomorphisms between completions Uqg and Ug family Drinfeld twists relating deformed classical coproducts can be chosen q.
