Regularization of non-coercive quasi variational inequalities. (English) Zbl 1006.49004

Summary: This paper is devoted to the regularization of quasi-variational inequalities. The quasi-variational inequality is considered with a multivalued operator. The operator involved is taken to be non-coercive and the data are assumed to be known approximately only. Under the assumption that the quasi-variational inequality be solvable, a weakly convergent approximation procedure is designed by means of the so-called Browder-Tikhonov regularization method.
