On convexity and quasiconvexity of extremal value functions in set optimization
Abstract: We study different classes of convex and quasiconvex set-valued maps defined by means of the lower-less order relation and the upper-less order relation. The aim of this paper is to formulate necessary and especially sufficient conditions for the convexity/quasiconvexity of extremal value functions.
Keywords: extremal functions, convex functions; convex set-valued maps; quasiconvex functions; quasiconvex set-valued maps.
Category 1: Convex and Nonsmooth Optimization (Generalized Convexity/Monoticity )
