摘要
通过在[1,∞)^(4)上引入一类实函数G,在乘积度量空间上给出一类隐式压缩映射的唯一不动点存在性定理,并举例说明所得结果的正确性.
By introducing a class of real function G on[1,∞)^(4),the author gave the existence theorems of unique fixed point for a class of implicit contractive mappings on multiplicative metric spaces,and gave an example to illustrate the correctness of the given result.
