Lie-Rinehart algebra acyclic Lie -algebroid

Abstract
We show that there is an equivalence of categories between Lie-Rinehart algebras over a commutative algebra and homotopy equivalence classes of negatively graded Lie -algebroids over their resolutions (=acyclic Lie -algebroids). This extends to a purely algebraic setting the construction of the universal -manifold of a locally real analytic singular foliation of Lavau-C.L.-Strobl. In particular, it makes sense for the universal Lie -algebroid of every singular foliation, without any additional assumption, and for Androulidakis-Zambon singular Lie algebroids. Also, to any ideal preserved by the anchor map of a Lie-Rinehart algebra , we associate a homotopy equivalence class of negatively graded Lie -algebroids over a complex computing . Several explicit examples are given.
