- In this paper we provide new results on even convexity and extend some others to the framework of general topological vector spaces. We first present a characterization of the even convexity of an extended real-valued function at a point. We then establish the links between even convexity and subdifferentiability and the Gamma-regularization of a given function. Consequently, we derive a sufficient condition for strong duality fulfillment in convex optimization problems. (C) 2015 Elsevier Inc. All rights reserved.
