Stability for parametric implicit vector equilibrium problems

In this paper, we consider a class of parametric implicit vector equilibrium problems in Hausdorff topological vector spaces where a mapping ff and a set KK are perturbed by parameters ϵϵ and λλ, respectively. We establish sufficient conditions for the upper semicontinuity and lower semicontinuity of the solution set mapping S:Λ1×Λ2→2XS:Λ1×Λ2→2X for such parametric implicit vector equilibrium problems.
