| Abstract: | Two alternative type theorems for nearly convexlike or * quasiconvex multifunctions are presented. They are used to derive Lagrangian conditions and duality results for vector optimization problems when the objectives and the constraints are nearly convexlike or * quasiconvex multifunctions. |
| Keywords: | Nearly convexlike functions * quasiconvex functions multifunctions duality vector optimization |
