RT Journal Article T1 Optimality and duality on Riemannian manifolds A1 Ruíz-Garzón, Gabriel A1 Osuna-Gómez, Rafaela A1 Rufián-Lizana, Antonio A1 Hernández-Jiménez, Beatriz K1 generalized convexity K1 Riemannian manifolds K1 efficient solutions K1 duality AB Our goal in this paper is to translate results on function classes that are characterized by the property that all the Karush-Kuhn-Tucker points are efficient solutions, obtained in Euclidean spaces to Riemannian manifolds. We give two new characterizations, one for the scalar case and another for the vectorial case, unknown in this subject literature. We also obtain duality results and give examples to illustrate it.
