The System of Vector Quasi-Equilibrium Problems with Applications

摘要

In this paper, we consider the system of vector quasi-equilibrium problems with or without involving Φ-condensing maps and prove the existence of its solution. Consequently, we get existence results for a solution to the system of vector quasi-variational-like inequalities. We also prove the equivalence between the system of vector quasi-variational-like inequalities and the Debreu type equilibrium problem for vector-valued functions. As an application, we derive some existence results for a solution to the Debreu type equilibrium problem for vector-valued functions.
