RT journal article T1 Optimality and Duality on Riemannian Manifolds A1 Ruiz Garzón, Gabriel A1 Osuna Gómez, Rafaela A1 Rufián Lizana, Antonio A1 Hernández Jiménez, Beatriz A2 Estadística e Investigación Operativa K1 Optimality K1 Riemannian manifolds AB Our goal in this paper is to translate results on function classes that arecharacterized by the property that all the Karush-Kuhn-Tucker points are e cientsolutions, obtained in Euclidean spaces to Riemannian manifolds. We give two newcharacterizations, one for the scalar case and another for the vectorial case, unknownin this subject literature. We also obtain duality results and give examples to illustrateit.
