Abstract

A singular (or Hermann) foliation on a smooth manifold MM can be seen as a subsheaf of the sheaf X\mathfrak{X} of vector fields on MM. 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.
