Solvability of Set-Valued Vector Optimization Problem
Jiawei Chen, Qi Xin Yin · 2009
In this paper, the authors introduce Dini derivative operator in the sense of set-values, establish the relations between set-valued vector quasi-variational inequality and set-valued vector optimization problems, and prove the existence of a weak minimum for a class of constrained set-valued vector optimization problem by making use of quasi-variational inequality and extending pseudo D-invex functions.
