Various Lipschitz-Like Properties for Functions and Sets. II: Subdifferential and Normal Characterizations

Rafael Correa; Pedro Gajardo; Lionel Thibault

Abstract

The present paper is a continuation of our previous article: Various Lipschitz-like properties of functions and sets. I: Directional derivative and tangential characterizations [SIAM J. Optim. 20(4) (2010) 1766–1785]. Here we provide diverse subdifferential and normal characterizations of K-directionally Lipschitzian functions and sets for bounded sets K of a Banach space.
