The aim of this paper is to establish variational principle on cone metric spaces and to give some existence theorems of solutions for equilibrium problems on cone metric spaces. We give some equivalences of an existence theorem of solutions for equilibrium problems on cone metric spaces.
Keywords: variational principle, equilibrium problem, upper semi-conti\-nuous, cone metric space
