This paper investigates the upper semicontinuity of the solution map for a parametric weak vector variational inequality associated to a c-hemicontinuous and weakly C-pseudomonotone operator. 1. Introduction and Preliminaries A vector variational inequality VVI in short was first introduced by Giannessi 1 in the setting of finite-dimensional Euclidean space. Later on it was studied and generalized to infinite-dimensional spaces. Existences of the solutions for VVI have been studied extensively in various versions see 2-6 and references therein. Stability of the solution map for VVI or vector equilibrium problems is an important topic in optimization theory. A great deal of papers have been denoted to study the semicontinuity and continuity of the solution maps see 7-18 and references therein. All results of the stability of the solution map for VVI in the literature are obtained based on continuity of the operator. It is well known that c-hemicontinuity is weaker than continuity. In this paper our aim is to investigate the upper semicontinuity of the solution map for a parametric weak vector variational inequality associated to a c-hemicontinuous and weakly C-pseudomonotone operator. Let X Y and W the spaces of parameters be .
