摘要 利用新的分析技巧,建立了任意实Banach空间中具随机误差的Ishikawa迭代法生成的序列{xn}强收敛于渐近半压缩映射的不动点的一些充要条件.作为应用,证明了Oslike和Aniagbosor最近的q-一致光滑实Banach空间中渐近半压缩映射的不动点的迭代逼近的一主要结果(它本身主要是1998年Osilike的一定理的一般化)能被延拓至任意实Banach空间上,并给出了Ishikawa迭代序列的误差估计,且所用证明方法比已有的简单. By using a new analysis technique, some sufficient and necessary conditions on strong convergence of sequence{xn }generated from the Ishikawa iteration method with random errors to fixed points of asymptotically demicontractive mappings are established in arbitrary real Banach spaces. As application, it is proved that a recent main result of Oslike and Aniagbosor (Which is itself a generalization of a theorem of Osilike(1998) ) concerning the iterarive approximation of fixed points of asymptotically demicontractive mappings in q-unifomly smooth real Banach space( 1〈q〈+∞)can be extended to arbitrary real Banach spaces. Error estimate of Ishikawa iterative sequence is given. Furthermore, the methods of proofs are quite different and simple.
