设E是满足Opial条件的一致凸Banach空间,C是E的非空闭凸子集,T1,T2…,TN:D→C是N个具有公共不动点的渐近非扩张映象。在不同条件下,该文证明了具误差的广义N步迭代序列分别弱收敛和强收敛于T1,T2,…TN的公共不动点。
Let E be a uniformly convex Banach space satisfying Opial's condition, C be a nonempty closed convex subset of E, and T1,T2..., TN:C→C be N asymptotically nonexpansive mappings with common fixed points. This paper proves that, under different conditions, the generalized N-step iterative sequence with errors converges weakly and converges strongly to a common fixed point of T1, T2…,TN respectively.
