In this thesis, first, we employ the fixedpoint theorem to establish the existence of solution of a class of generalized vector quasi-variational-like inequality over product sets.
本文首先研究了一类积集上的广义向量拟类变分不等式问题，使用不动点定理给出了它的解的存在性结果。

A section theorem, a minimax inequality and a generalized fixedpoint theorem where the underlying space is a product space of two topological vector Spaces, are given.
给出了两个拓扑向量空间的乘积空间上截口定理，极小极大不等式及一个推广的不动点定理。

By using the collectively fixedpoint theorem, the existence theorems of some new system of vector equilibrium problems are obtained.
