## Idea

The monoidal Dold-Kan correspondence relates algebras over an operad in abelian simplicial groups with algebras over an operad in chain complexes.

This generalizes the monoidal Dold-Kan correspondence.

## Statements

• In (Mandell) a Quillen equivalence between E-infinity algebras in chain complexes and in simplicial abelian groups is demonstrated.

• In (Richter) it is shown that for any reduced operad $\tilde \mathcal{O}$ in $Ch_\bullet^+(Mod)$, which is a resolution of an operad in $Mod$, the inverse map $\Gamma : Ch_\bullet^+ \to sAb$ of the Dold-Kan correspondence lifts to a Quillen adjunction between homotopy $\mathcal{O}$-algebras in $Ch_\bullet(Mod)$ and in $Mod^{\Delta^{op}}$. (Around therem 5.5.5). It is not shown yet if or under which conditions this is a Quillen equivalence.

A Quillen equivalence between $E_\infty$ dg-algebras and $E_\infty$ simplicial algebras is given in

where the Moore complex functor is the right adjoint.

A construction that allows its inverse to be part of the adjunction is in
