摘要
度量空间X上的非扩张型映射不一定存在不动点,Ljubomir研究了X上一类非扩张型映射并给出了相应的不动点定理。在Ljubomir研究的基础上提出并证明了一个非扩张型映射的不动点定理。
A non-expansive mapping needn＇t have fixed points on metric spaces.Ljubomir investigated a class of non-expansive type mappings and fixed point＇s theorem.In this paper,a new class of non-expansive type mappings and fixed points theorem were given.Meanwhile,the fixed points theorem about the new mappings was proved.
