On generalized vector pre-variational and pre-quasivariational inequalities ✩

In this paper, we consider generalized vector pre-variational inequality problems as well as vector pre-quasivariational inequality problems in abstract space setting. We establish several existence results for these two classes of problems by employing the Ky Fan lemma and a scalarization technique, respectively.  2004 Elsevier Inc. All rights reserved.
