Abstract

In this paper, we consider a problem related to a generalized Nash equilibrium problem, known as, a quasi-equilibrium problem. Generally, such problem is discussed using a real valued bifunction. The so called vector quasi-equilibrium problem is the extension to the vector setting of the quasi-equilibrium problem. Therefore, we consider a sequence generated from a modified extragradient method, called an alternative extragradient method, for obtaining the convergence theorem to a solution of the vector quasi-equilibrium problem.
