In this note for every \(S\)-metric space \((X,S),\) we define a new \(S\)-metric \({S}_{H}\) called Hausdorff S-metric on \(CB(X)\) and show that if \((X,S)\) is complete, \((K\left(X\right), {S}_{H})\) is complete too, where K(X) is the set of all compact nonempty subsets of \(X\) and the notion of weak contraction multi-valued mappings on complete metric spaces (Kritsana Neammanee & Annop Kaewkhao, 2011) is generalized to complete \(S\)-metric spaces. This idea is used to establish some fixed-point theorems for weak contractive multi-valued mappings from \((X,S)\) into \((CB\left(X\right),{S}_{H})\).

多值弱收缩映射的$$ {S} _ {H} $$ SH-度量空间和不动点定理

在这份说明中,每\(S \) -metric空间\((X,S),\),我们定义了一个新的\(S \) -metric \({S} _ {H} \)称为豪斯多夫S-指标在\(CB(X)\)上并显示,如果\((X,S)\)已完成,则\((K \ left(X \ right),{S} _ {H})\)也已完成,其中K(X)是\(X \)的所有紧致非空子集的集合,并且对完整度量空间上的弱压缩多值映射的概念(Kritsana Neammanee&Annop Kaewkhao,2011)被广义化为完成\(S \) -公制空格。这个想法是用来建立一些定点定理,用于从\((X,S)\)\((CB \ left(X \ right),{S} _ {H})\)
