The purpose of this paper is to investigate the problems of the well-posedness for a system of mixed quasivariational-like inequalities in Banach spaces. First, we generalize the concept ofα-well-posedness to the system of mixed quasivariational-like inequalities, which includes symmetric quasi-equilibrium problems as a special case. Second, we establish some metric characterizations ofα-well-posedness for the system of mixed quasivariational-like inequalities. Under some suitable conditions, we prove that theα-well-posedness is equivalent to the existence and uniqueness of solution for the system of mixed quasivariational-like inequalities. The corresponding concept ofα-well-posedness in the generalized sense is also considered for the system of mixed quasivariational-like inequalities having more than one solution. The results presented in this paper generalize and improve some known results in the literature.

In this paper, well-posedness for parametric generalized strong vector quasi-equilibrium problems is studied. The corresponding concept of well-posedness in the generalized sense is also investigated for the parametric generalized strong vector quasi-equilibrium problem. Under some suitable conditions, we establish some characterizations of well-posedness for the parametric generalized strong vector quasi-equilibrium problem.
