Abstract:

A kind of generalized gradient for set-valued map is introduced in ordered Banach spaces. Under the connected condition, its existence is proved by the separation theorem for convex sets. As an application, the optimality necessary and sufficient conditions of strong-efficient solution for set-valued optimization problem are established in terms of the generalized gradient.

Key words: Set-valued optimization, Contingent derivative,  Strong-efficiency, Generalized gradient, Optimality condition
