S-度量空间中(Ψ-Φ)-弱压缩多值映射的不动点定理

Fixed Points of Multi-valued Mappings for(Ψ-Φ)-Weak contractions in S-metric Spaces

基于(Ψ-Φ)-弱压缩的概念,研究了在S-度量空间中(Ψ-Φ)-弱压缩多值映射的不动点问题,建立了此类映射条件下的不动点定理,所得的结果改进和推广了S-度量空间中多值映射下的一些不动点定理,并且补充了一些已有文献的结果.

Based on the concepts of(Ψ-Φ)-weak contractions,we consider some problems of fixed points for(Ψ-Φ)-weak contractive multi-valued mapping in a setting of S-metric spaces.Some fixed point theorems for this mapping are established.Our results improve and generalize some fixed point theorems for multi-valued mapping in S-metric spaces,and complement some previous results.
