On a class of general variational inequalities. (English) Zbl 1169.49007
Summary: We introduce a new class of variational inequalities, which is called the general variational inequality. We also introduce a new class of Wiener-Hopf equations. Essentially using the projection technique, we establish the equivalence between the general variational inequalities and fixed point problems as well as with the Wiener-Hopf equations. This equivalent formulation is used to suggest and analyze some iterative algorithms for solving the general variational inequalities. We also discuss the convergence analysis of these iterative methods. Several special cases are also discussed. Our methods of proofs are very simple as compared with other techniques.
