On existence of a solution for the system of generalized vector quasi-equilibrium problems with upper semicontinuous set-valued maps

Abstract

We introduce a new model of the system of generalized vector quasi-equilibrium problems with upper semicontinuous set-valued maps and present several existence results of a solution for this system of generalized vector quasi-equilibrium problems and its special cases. The results in this paper extend and improve some results in the literature.
