      Abstract

      We show that a certain condition regarding the separation of points by Lipschitz functions is useful in extending a given Lipschitz function from a subspace of a separable Banach space to the whole space so that the extension function has a maximal Clarke subdifferential. We then establish connections between this separation property and the rotundity properties of the norm on the Banach space.
