摘　　要：在更一般的条件下研究了Banach空间中渐近拟非扩张型映象的具误差或混合误差的Ishikawa迭代序列强收敛到其不动点的充分必要条件.The purpose of this paper is to study the necessary and sufficient conditions for the Ishikawa Iterative sequences with mixed errors for asymptotically quasi-nonexpansive type mippings in Banach spaces to converge to a fixed point in Banach spaces.
