Abstract:

In real ordered linear spaces, an equivalent characterization of generalized cone subconvexlikeness of set‐valued maps is firstly established. Secondly, under the assumption of generalized cone subconvexlikeness of set‐valued maps, a scalarization theorem of set‐valued optimization problems in the sense of ϵ‐weak efficiency is obtained. Finally, by a scalarization approach, an existence theorem of ϵ‐global properly efficient element of set‐valued optimization problems is obtained. The results in this paper generalize and improve some known results in the literature.
