In this paper, we consider an extension of the notion of well-posedness by
perturbations, introduced by Zolezzi for a minimization problem, to a class
of variational-hemivariational inequalities with perturbations in Banach
spaces, which includes as a special case the class of mixed variational
inequalities. Under very mild conditions, we establish some metric
characterizations for the well-posed variational-hemivariational inequality,
and show that the well-posedness by perturbations of a
variational-hemivariational inequality is closely related to the
well-posedness by perturbations of the corresponding inclusion problem.
Furthermore, in the setting of finite-dimensional spaces we also derive some
conditions under which the variational-hemivariational inequality is strongly
generalized well-posed-like by perturbations.
