Abstract

This paper studies $$\varepsilon $$ ε -efficiency in multiobjective optimization by using the so-called coradiant sets. Motivated by the nonlinear separation property for cones, a similar separation property for coradiant sets is investigated. A new notion, called Bishop–Phelps coradiant set is introduced and some appropriate properties of this set are studied. This paper also introduces the notions of $$\varepsilon $$ ε -dual and augmented $$\varepsilon $$ ε -dual for Bishop and Phelps coradiant sets. Using these notions, some scalarization and characterization properties for $$\varepsilon $$ ε -efficient and proper $$\varepsilon $$ ε -efficient points are proposed.
