Abstract:

The aim of this article is to present new existence results for globally efficient solutions of a strong vector equilibrium problem given by a sum of two functions via a generalized KKM principle,and to establish the connectedness of the solutions set.

Key words: KKM principle, equilibrium problems given by a sum, globally efficient solution, near C-subconvexlikeness
