Abstract

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