摘要
在完备的锥b-度量空间中,利用迭代法研究了广义c-距离下两类扩张映射和压缩映射不动点的存在性问题,并且通过简化映射系数,得到了相关推论。所得结果改进并推广了锥度量空间中的相关结论,且给出了具体应用。
In this paper,the existence of fixed point of two kinds of expanding mappings and contractive mappings in generalized c-distance is studied by constructing iterative sequence in perfect cone b-metric spaces,and relevant inferences are achieved by simplifying coefficient of the mappings. The results directly improve and generalize relevant theorems in cone metric spaces,and result in the concrete application.
