Abstract:
In this paper, we consider variational inequality problem over product of sets, which is equivalent to the system of variational inequalities. By introducing the concept of densely relative pseudomonotone operators, we establish the existence of a solution of our problem. As an application of our results, we prove the existence of a coincidence point of two families of nonlinear operators.
