偏距离空间上四个映射的公共不动点的存在性与唯一性

Existence and Uniqueness of Common Fixed Point for Four Mappings on Partial Metric Spaces

该文证明了偏距离空间上满足广义非线性压缩型的四个映射的公共不动点定理.最后,举例说明了该文压缩条件确实改进了目前一些文献中压缩条件.

In this work, we shall prove that a common fixed point theorem for four mappings satisfying a generalized nonlinear contraction type condition on partial metric spaces. Finally, we give two examples to show that our contractive conditions is real improvement for the contractive conditions used in the literature.
