一类非扩张型映象不动点定理的推广

Generalization of Fixed Point of a Class of Non-expansive-type Mapping

在完备度量空间中,将Ovidiu Popescu定理中的非负实数a,b,c改为了非负函数a,b,c,推广了相应结论,并证明了T的不动点的存在性和唯一性.

In a complete metric space, the non-negative real number a, b, c in Ovidiu Popescu Theorem are changed to non-negative function a, b, c, the corresponding conclusions are generalized and the existence and uniqueness of the fixed point of T are verified.
