Abstract

In this paper, we perform a general analysis of stability and well-posedness for a parametric quasivariational inequality problem. Various sufficient conditions ensuring stability, in terms of semicontinuity and closedness of the parametric solution set map are established. Metric characterizations of Levitin–Polyak (LP) well-posedness via approximate solutions sets are also derived. A key result characterizing LP well-posedness in terms of the upper semicontinuity of the approximate solution set has been proved.
