Banach空间中渐近非扩张映象的修正Reich-Takahashi型迭代法的强收敛性
On the Strong Convergence of the Modified Reich-Takahashi Type Iteration Method for Asymptotically Nonexpansive Mappings in Banach Spaces
【摘要】 设E是具有一致正规结构的实Banach空间,其范数是一致Gateaux可微的.设D 是E的非空有界闭凸子集,T:D→D是渐近非扩张映象.该证明了,在一些适当的条件下,修正的Reich-Takahashi型迭代法强收敛到渐近非扩张映象T的不动点.
【Abstract】 Let E be a real Banach space with uniform normal structure, whose norm is uniformly Gateaux differentiable. Let D be a nonempty bounded closed convex subset of E and T : D→D be an asymptotically nonexpansive mapping. It is shown that under some suitable conditions, the modified Reich-Takahashi type iteration method converges strongly to a fixed point of T.
