On the Finslerian entropy of smooth distributions and Stefan-Sussman foliations

Starting from the definition of the entropy of a growing family of distances on a compact metric space, we define the Finslerian entropy of a smooth distribution and of a Stefan-Sussman foliation. This notion of entropy is a generalization of most classical topological entropies on a Riemannian compact manifold: the entropy of a flow ([2]), of a regular foliation ([4]), of a regular distribution ([1]) and more generally of a ”geometrical structure” ([5]). In this way, we obtain the nullity of the Finslerian entropy of a controllable distribution and of a singular Riemannian foliation.
