Lie $\infty$-algebroids and singular foliations

Abstract: A singular (or Hermann) foliation on a smooth manifold $M$ can be seen as a subsheaf of the sheaf $\mathfrak{X}$ of vector fields on $M$. We show that if this singular foliation admits a resolution (in the sense of sheaves) consisting of sections of a graded vector bundle of finite type, then one can lift the Lie bracket of vector fields to a Lie $\infty$-algebroid structure on this resolution, that we call a universal Lie $\infty$-algebroid associated to the foliation. The name is justified because it is isomorphic (up to homotopy) to any other Lie $\infty$-algebroid structure built on any other resolution of the given singular foliation.
