| 摘 要： | 本文研究在任意的实Banach空间中用带误差的修改的Ishikawa迭代序列来逼近一致Lipschitz的渐近伪压缩映象的不动点的问题.在去掉限制limn→∞βn=0之下,证明了张石生教授的结果(见文1])仍真.另一方面,也把他的结果推广到了带误差的修改的Ishikawa迭代序列的情形.

| Abstract: | The purpose of this paper is to investigate the problem of approximating to the fixed points of uniformly Lipschitzian asymptotically pseudocontractive mappings in an arbitrary real Banach space by the modified Ishikawa iterative sequences with errors. Under the condition of removing the restriction limn→∞βn = 0 we prove that Professor Zhang Shisheng's results (Acta Math. Appl. Sinica, 2001, 24 (2): 236-241) remain true. On the other hand, we also extend his results to the case of the modified Ishikawa iterative sequences with errors. |
