Abstract:
This paper deals with the characterizations of solutions for vector equilibrium problems by means of conjugate duality. In order to introduce set-valued mappings depending on the data, but not on the solution sets of vector equilibrium problems we use Fenchel duality. By this approach we obtain also some gap functions for the so-called weak vector variational inequality problems.
