Nonlinear Split Ordered Variational Inequality Problems

The concept of nonlinear split ordered variational inequality problems on partially ordered vector spaces is a natural extension of linear split vector variational inequality problems on Banach spaces. The results about nonlinear split ordered variational inequality problems are immediately applied to solving nonlinear split vector optimization problems. In this paper, we prove the solvability of some nonlinear split ordered variational inequality problems by using some fixed point theorems on partially ordered spaces, in which the considered mappings may not be required to have any type of continuity and they just satisfy some order-monotonic conditions. As applications of the results about nonlinear split ordered variational inequality problems, we study solvability of some nonlinear split variational inequality problems and linear split variational inequality problems on partially ordered vector spaces and partially ordered Banach spaces.
