摘要：

We construct cup products of two different kinds for Hopf-cyclic cohomology When the Hopf algebra reduces to the ground field our first cup product reduces to Connes' cup product in ordinary cyclic cohomology. The second cup product generalizes Connes-Moscovici's characteristic map for actions of Hopf algebras on algebras. (C) 2004 Academie des sciences. Published by Elsevier SAS. All rights reserved.
