Abstract:In this paper, we characterize the nonemptiness of the set of weak minimal elements for a nonempty subset of a linear space. Moreover, we obtain some existence results for a nonconvex set-valued optimization problem under weaker topological conditions.
Introduction and preliminariesLet Y be a real linear space ordered by a convex cone C ⊆ Y which is assumed to be proper; i.e., {0} = C = Y . Let K be a nonempty set and F : K ⇒ Y be a set-valued mapping with nonempty values. A general form of set-valued optimiza… Show more
