Characterizations of $alpha$-well-posedness for parametric quasivariational inequalities defined by bifunctions

Abstract

The purpose of this paper is to investigate the well-posedness issue of parametric quasivariational inequalities defined by bifunctions. We generalize the concept of $alpha$-well-posedness to parametric quasivariational inequalities having a unique solution and derive some characterizations of $alpha$-well-posedness. The corresponding concepts of $alpha$-well-posedness in the generalized sense are also introduced and investigated for the problems having more than one solution. Finally, we give some sufficient conditions for $alpha$-well-posedness of parametric quasivariational inequalities
