摘要
应用模糊度量满足三角不等式的基本概念及分析方法,研究完备模糊度量空间中Ciric-Altman型映射不动点的存在性问题,在一定条件下于模糊度量空间中给出了两个新的非唯一不动点定理,扩展了相关结果.
The existence of fixed points of Ciric-Altman type mappings in complete fuzzy metric spaces is studied by using the basic concept of fuzzy metric satisfying triangular inequalities and analysis method. Two new nonunique fixed point theorems are established in fuzzy metric spaces,and the theorems extend the previous results.
