Abstract:

In this paper, we introduce the concept of weak S-optimal solution and S-subconvexlikeness of vector optimization with set-valued maps and obtain an alternative theorem in a real locally Hausdorff topological vector space. Furthermore, under the assumption of S-subconvexlikeness, we establish scalarization theorem for weak S-efficient solution. We also give some examples to illustrate the main results.

Key words: vector optimization, S-subconvexlikeness, weak S-efficient solution, alternative theorem, scalarization theorem
