摘要
指出了文献[Int.J.Pure Appl.Math.,2011,73(2):159-164]中给出的定理的错误证明,得出复值度量空间上满足分式收缩条件的四个映射的唯一公共不动点定理,并给出了若干更一般形式的结论及不动点定理.所得结论推广和改进了一些已知结果.
We point out a false proof of a given theorem in [Int. J. Pure Appl. Math.,2011, 73(2): 159-164], and obtain unique common fixed theorems for four mappings satisfying a rational contractive condition on complex valued metric spaces and give some more general results and fixed point theorems. The obtained results generalize and improve some known conclusions.
