### A remarkable DGmodule model for configuration spaces

#### Abstract

Let $M$ be a simply connected closed manifold and consider the (ordered) configuration space $F(M,k)$ of $k$ points in $M$. In this paper we construct a commutative differential graded algebra which is a potential candidate for a model of the rational homotopy type of $F(M,k)$. We prove that our model it is at least a $Σk$–equivariant differential graded model.

We also study Lefschetz duality at the level of cochains and describe equivariant models of the complement of a union of polyhedra in a closed manifold.
