## THE EKELAND VARIATIONAL PRINCIPLE FOR HENIG PROPER MINIMIZERS AND SUPER MINIMIZERS

In this paper we consider, for the first time, approximate Henig proper minimizers and approximate super minimizers of a set-valued map F with values in a partially ordered vector space and formulate two versions of the Ekeland variational principle for these points involving coderivatives in the senses of Ioffe, Clarke and Mordukhovich. As applications we … Read more
