Abstract:
In this paper we study a measure-theoretic notion of differentiability introduced in a paper by Le Bris and Lions, in connection with the differentiability properties of the flow associated to a Sobolev vector field. We characterize in various ways this differentiability property, showing through an example that it is strictly weaker than the classical approximate differentiability.
