RT info:eu-repo/semantics/article T1 Two-Variable Domination Structures and Applications in Vector Optimization A1 Ngoan, Dang Thi A1 Gutiérrez, César A1 An, Duong Thi Viet K1 Variable domination structure K1 Vector optimization K1 Nondominated solutions K1 Minimal solutions K1 Nonlinear scalarization functions AB In this paper, we introduce and study domination structures in real topological Hausdorff linear spaces that take into account the two involved points at each comparison. These binary relations are then applied to define notions of minimizer of a set and optimality concepts for vector optimization problems in the usual way, and their basic properties are obtained. Results on nonlinear scalarization to characterize them are also stated, which can be applied to vector optimization problems with variable ordering structures where the known ones do not work. Comparisons with results of the literature and illustrative examples are given as well.
