Abstract:

We define a multiplication on the cyclic homology of a commutative, cocommutative bialgebra $H$ with “superproduct.” In the case when $H$ is a field of characteristic zero the cyclic homology becomes a polynomial algebra in one generator. (The Loday-Quillen multiplication is trivial in that case.)
