On the Multiplicative Structure of Topological Hochschild Homology

M. Brun, Z. Fiedorowicz, R. M. Vogt

Published 2004-10-16, updated 2007-06-19Version 2

We show that the topological Hochschild homology THH(R of an E_n-ring spectrum R is an E_{n-1}-ring spectrum. The proof is based on the fact that the tensor product of the operad Ass for monoid structures and the the little n-cubes operad is an E_{n+1}-operad, a result which is of independent interest.
