乘积b-度量空间中扩张型映象的公共不动点定理

A Common Fixed Point Theorem of Expanding Mappings in Multiplicative b-metric Spaces

在完备的乘积b-空间中,建立一个扩张型条件,研究了公共不动点的存在性和唯一性,从而得到了一个新的公共不动点定理,改进了相关文献的结果.

In complete multiplicative b-metric spaces, by establishing a new expanding condition, the existence and the uniqueness of the common fixed point are studied, a new common fixed point theorem is obtained, which improves the corresponding results in some references.
