A natural example of quotient spaces are the ones given by a singular foliation on a manifold. In this case we have a canonical groupoid to model it, the holonomy groupoid.
This talk gives an introduction on singular foliations, it explains the construction of the Holonomy groupoid of a singular foliation and discusses the definition of Morita equivalence for singular foliations.
