摘要
设E是实Banach空间,K是E的非空闭子集,T:KK是Lipschitz严格伪压缩映象.证明了具误差的Ishikawa迭代序列强收敛到T的唯一不动点.另外,相关结果也证明了,当T:EE是Lipschitz强增生算子时,具误差的Ishikawa迭代序列强收敛到方程Tx=f的唯一解.
Let E be an arbitrary real Banach space and K be a nonempty colssed subset of E. Let T: KK be a Lipschitz strictly pseudocontractive mapping. We prove the Ishikawa iterative sequence with errors converges strongly to the unique fixed point of T. Furthermore, in a related result, it is shown that if I: EE is a Lipschitz strongry accretive operator, then the Ishikawa iterative sequence with errors converges strongly to the unique solution of the equation Tx=f.
