2-度量空间上两个膨胀映射的重合点和公共不动点

Coincidence points and common fixed points for two expansive mappings on 2-metric spaces

推广和改进了一个已知的2-度量空间上满足第二膨胀条件的两个映射的公共不动点存在定理,然后利用新的方法研究了满足另一类膨胀条件的两个映射的公共不动点存在问题,结果表明,本文所用方法明显优于文献[6,9-10]中的方法.

We generalize and improve a known existence theorem of common fixed points for two mappings satisfying II-expansive conditions in 2-metric spaces,and use a new method to discuss the existence problems of common fixed points for mappings with another type expansive condition.The results show that our method is very better than that in references[6,9-10].
