Connectedness of Solution Sets for Weak Vector Variational Inequalities on Unbounded Closed Convex Sets

Abstract EN

We study the connectedness of solution set for set-valued weak vector variational inequality in unbounded closed convex subsets of finite dimensional spaces, when the mapping involved is scalar C-pseudomonotone.

Moreover, the path connectedness of solution set for set-valued weak vector variational inequality is established, when the mapping involved is strictly scalar C-pseudomonotone.

The results presented in this paper generalize some known results by Cheng (2001), Lee et al.

(1998), and Lee and Bu (2005).
