均衡问题是变分不等式与相补问题的有意义推广.提出了三类涉及集值映射的广义向量拟均衡问题.在适当的凸性要求与连续性条件下,利用Oettli引进的数值化函数、著名的Kneser极小极大定理和连续单位分解定理,讨论了这些集值映射的广义向量拟均衡问题解的存在性,所得到的结论推广和发展了近期一些研究结果.
Equilibrium problem is the valuable generalization of variational inequality and its complementary. In this paper, three classes of generalized vector quasi - equilibrium problems with set - valued mappings are studied. By the scalarization function which was proposed by Oettli, the famous Kneser's min - max theorem and the theorem of continuous partition of unity, the existence theorems of solution for them are derived under suitable conditions of convexity and continuity.
