类距离空间中关于循环映射的公共不动点定理

Common Fixed Point Theorem for Cyclic Mappings in Metric-like Spaces

在0-σ-完备的类距离空间中,证明了一类循环压缩映射的公共不动点定理,其中压缩条件包含了二元变距离函数.结果改正并推广了Akram等人最近的结果.

In the setting of O-a-complete metric-like spaces, we establish a common fixed point theorem for cyclic contractive mappings, where contractive condition contains a gen- eralized distance altering function. Our result rectifies and improves the recent result of Akram et al.
