Optimally Local Dense Conditions for the Existence of Solutions for Vector Equilibrium Problems
Sirous Moradi, Maryam Shokouhnia, Somaye Jafari · International journal of nonlinear analysis and applications · 2019
In this paper, by using C-sequentially sign property for bifunctions, we provide sufficient conditions that ensure the existence of solutions of some vector equilibrium problems in Hausdorff topological vector spaces which ordered by a cone. The conditions which we consider are not imposed on the whole domain of the operators involved, but just on a locally segment-dense subset of the domain.
