Abstract

This paper investigates a vector equilibrium problem in a topological vector space. By employing a scalarization approach together with suitable assumptions, sufficient conditions for the connectedness of the solution set of the considered problem are established. The obtained results are new in comparison with existing results in the literature and make a significant contribution to the study of solution properties in equilibrium problem theory.

Keywords: Connectedness, scalarization method, vector equilibrium problem, weakly efficient solution
