英文摘要：

The existence and connectedness of solutions for weak vector variational inequalities and their scalarization with a C-monotone mapping from a topological vector space to continuous linear mapping space L（X, Y） are shown. With the C-weak hemicontinuity and C-monotonicity for a mapping, and setvalued mapping fixed point theorems, the connectedness are derived by discussing the properties of set-valued mapping induced by solution sets of a scalarization variational inequality related to the weak vector variational inequalities.
