Abstract: The aim of this paper is to present new characterizations of explicitly cone-quasiconvex vector functions with respect to a polyhedral cone of a finite-dimensional Euclidean space. These characterizations are given in terms of classical explicit quasiconvexity of certain real-valued functions, defined by composing the vector-valued function with appropriate scalarization functions, namely the extreme directions of the polar cone or some nonlinear scalarization functions, currently used in vector optimization.

Keywords: Generalized convex vector functions; polyhedral cones; extreme directions; nonlinear scalarization function

Category 1: Convex and Nonsmooth Optimization (Generalized Convexity/Monoticity )
