DUALITY THEOREM AND VECTOR SADDLE POINT THEOREM FOR NONSMOOTH VECTOR OPTIMIZATION PROBLEM
Abstract
In this paper, sufficient optimality conditions and duality results for nonsmooth vector optimization problems are given under near invexity and infineness assumptions. Also, weak vector saddle-point theorems are obtained under near invexity-infineness assumptions.
