(ψ,φ)-g-弱压缩映射的公共耦合不动点定理

Coupled Coincidence Point Theorems for(ψ,φ)-g-Weakly Contraction in Partially Ordered Metric Spaces

在完备偏序度量空间中引入(ψ,φ)-g-弱压缩映射,得到关于该映射的公共耦合不动点定理.这些结果推广了近年来一些关于公共耦合不动点的结论,并给出一个例子用于佐证.

In this paper,we introduce the concept of (ψ,φ)-g-weak contractive mapping and establish two coupled coincidence point theorems for such mappings in an partially ordered complete metric spaces.Pres-ented theorems are generalizations of the recent coincidence fixed point theorems.An example is also in-troduced.
