摘要:

引入带有集值映射的向量拟均衡问题的f-有效解的概念,并在Hausdorff拓扑向量空间中利用标量化的方法研究了向量拟均衡问题解集的连通性。

Abstract:

The concept of f-efficient solution is introduced for a vector quasi-equilibrium problem with set-valued mappings. The conectedness of solution set for the vector quasi-equilibrium problem is studied by means of a scalarized methhod in the setting of Hausdorff topological vector spaces.

Key words: vector quasi-equilibrium problem; connectedness of solution set; fixed-point theorem; separation theorem of convex set
