Differentiability of convex functions on sublinear topological spaces and variational principles in locally convex spaces
From the authors' abstract: This paper presents a type of variational principles for real-valued \(w^*\)-lower semicontinuous functions on certain subsets in duals of locally convex spaces, and resolves a problem concerning differentiability of convex functions on general Banach spaces.
