摘要: 基于对弱伪连续实值函数的研究, 提出向量值函数关于锥的弱伪连续定义, 并建立了向量值函数$R_+^k$弱伪连续与实值函数弱伪连续的对应关系. 作为弱伪连续向量值函数的应用, 给出了弱伪连续下的向量值Ky Fan点的存在性定理, 并通过该定理证明了伪连续向量值支付下的多目标博弈弱Pareto-Nash平衡点的存在性定理.

Abstract: In this paper, based on the study of pseudocontinuous real-valued functions, a definition of the weakly pseudocontinuous of vector-valued functions on cone is proposed. And a weakly pseudocontinuous relationship is established between the vector-valued functions on $R_+^k$ and the real-valued functions. As an application of the weakly pseudocontinuous of vector-valued functions on cone, the existence theorem of weakly Pareto-Nash equilibrium in multi-objective games with the pseudocontinuous payoffs is proved by the improved vector-valued Ky Fan points.

Key words: weakly pseudocontinuous, vector-valued functions, vector-valued Ky Fan points, multi-objective games
