Abstract.
MacLane homology of a ring R is the Hochschild homology of the so called cubical construction \(Q_*(R)\), which is a chain-algebra. If we take a commutative ring R, the Dixmier product on \(Q_*(R)\) is no longer commutative. The main result of this paper is that it is commutative up to higher homotopies, i.e. that it is an \(E_{\infty}\)-algebra. The \(E_{\infty}\)-operad which acts on \(Q_*(R)\) is constructed by using the analogue of the \(Q_*\)-complex in the context of finite sets. For the precise notation of an operad action on these complexes the definition of an \( E_{\infty}\)-monoidal functor is introduced.
