Abstract
In this paper, we apply a version of Kakutani’s fixed point theorem to study weak and Pareto quasi-equilibrium problems. Some sufficient conditions on the existence of solutions of weak and Pareto quasi-equilibrium problems with multivalued mappings are shown. As applications, we give several results on the existence of solutions to vector quasivariational inequalities problems and vector Pareto quasi-saddle problems.
