On the stability of generalized vector quasivariational inequality problems. (English) Zbl 1003.47049
Summary: We obtain some stability results for generalized vector quasivariational inequality problems. We prove that the solution set is a closed set and establish the upper semicontinuity property of the solution set for perturbed generalized vector quasivariational inequality problems. These results extend those obtained in {\it L. Gong}, J. Optimization Theory Appl. 70, No. 2, 365-375 (1991; Zbl 0737.49010). We obtain also the lower semicontinuity property of the solution set for perturbed classical variational inequalities. Several examples are given for the illustration of our results.
