According to the existence results of general equilibrium problems and vector equilibrium problems have been studied more and more. Inspired and motivated by these research results, this paper is devoted to study systematically a class of equilibrium problems, which is unify and extension of a large number of known equilibrium problems and variational inequalities problems. The research is carried on from three aspects.Firstly, in finitely continuous topological spaces, we introduce four new types of the system of generalized vector quasi-equilibrium problems, and we derive some existence results of a solution for the system of generalized vector quasi-equilibrium problems via the maximal element theorems in product finitely continuous topological spaces.Secondly, in complete metric spaces, we provide the Ekeland variational principle to equilibrium problems with set-valued maps. And via the Ekeland variational principle, existence results for vector equilibrium problem with set-valued maps and the system of vector equilibrium problem with set-valued maps.
针对一般的均衡问题和向量均衡问题解的存在性,已有许多研究成果,受这些成果的启发,本文主要从理论上较为系统地研究了一类均衡问题,它统一和推广了许多已有的均衡问题和变分不等式问题,研究分有三个方面;首先,在有限连续拓扑空间中,我们提出了四类广义向量拟均衡系,并借助于有限连续拓扑空间中的极大元定理讨论了这四类均衡系问题的解的存在性问题,然后,在完备度量空间中,我们给出了关于集值均衡问题的Ekeland变分原理,并利用Ekeland变分原理分别讨论了集值向量均衡问题和集值向量均衡系问题的解的存在性。
