摘要
W.Vpetryshyn和T.EWiuiamson[1]研究了度量空间上正则映射和拟非展映射的不动点集的性质.GiuseppeMarini[2]和Rainer.Wittmann[3]等人用各种叠代方法去逼近不动点.在本文中,我们引进了强渐近有界映射的概念并证明了一个不动点定理.
in this paper,we intoroduce the concept of strongly asymptotically boanded mapping in metric space and prove fixed point theorem.Definition A mapping T.on a metric space (X,d)is said to be strangly asympto tically bounded atx if each x in X,there exists a positive inteqer k(x) sach that d(T'x,
