摘　　要：在新的条件之下,研究了渐近拟非扩张型的映像具误差项的Ishikawa迭代逼近不动点的问题,同时给出了强收敛定理。在主要结果中,满足有界Ishikawa迭代序列{xn}的某些条件下,不需要集合K和T的值域的有界性。In the new conditions,we study the asymptotically quasi-nonexpansive mapping with errors Ishikawa iterative approximation problem of fixed points,and the strong convergence theorrem is given.In our main results,bounded subsequence under Ishikawa iterative sequence with some conditions,the assumption that set K and the range of the mapping T are bounded is not needed.
