摘要
在一般实Banach空间中,研究有限个渐近伪压缩映象簇和有限个渐近非扩张映象簇的不动点的迭代逼近问题,给出带随机误差的修正的Ishikawa迭代序列强收敛的充要条件,所得结果改进和推广了朱玲娣(2002年),王朝和刘理蔚(2006年)等人的近期的相应结果.
The iterative approximation problems of fixed points are studied for a finite family of asymptotically pseudocontractive mappings and a finite family of asymptotically non - expansive mappings in general real Banach spaces. Some necessary and sufficient conditions are given for modified Ishikawa iterative sequence with random errors to converge to fixed points. These results improve and extend the corresponding results of Zhu （2002）, Wang and Liu （2006）, and other authors.
