非扩张映射的逼近不动点

Approximating fixed points of nonexpansive mappings

对映射其中α１≥０，α０＞０，α１＞０，证明了当Ｔ是非扩张映射时，Ｓ在Ｂａｎａｃｈ空间中的毕卡迭代过程收敛到Ｔ的一个不动点．

In this paper,we consider a mapping S of the from where αi≥0,α0>0,α1>0,Show that the Picard iterates of S converge to a fixed point of T in a Banach sauce when T is nonexpadrive.
