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 𝒪˜\tilde \mathcal{O} in Ch +(Mod)Ch_\bullet^+(Mod), which is a resolution of an operad in ModMod, the inverse map Γ:Ch +sAb\Gamma : Ch_\bullet^+ \to sAb of the Dold-Kan correspondence lifts to a Quillen adjunction between homotopy 𝒪\mathcal{O}-algebras in Ch (Mod)Ch_\bullet(Mod) and in Mod Δ opMod^{\Delta^{op}}. (Around therem 5.5.5). It is not shown yet if or under which conditions this is a Quillen equivalence.
