本文研究了向量均衡问题.利用在锥度量空间中给出的Ekeland变分原理,我们推导了向量均衡问题解的存在性定理.本文的结论是新的并推广了相关文献中的结论.
In this paper, we study the vector equilibrium problem. By using the new Ekeland's principle that we introduce in cone metric space, we derive an existence theorem of solution for vector equilibrium problem. The results obtained in this paper are new and improve the recent ones announced by many others.
