Banach空间中两个非扩张非自映象对公共不动点的逼近
Approximating Common Fixed Point of Two Non-self Nonexpansive Mappings in Banach Spaces
【摘要】 设E是一致凸的Banach空间,C是E的非空有界闭凸子集而且是E的非扩张收缩核.设S,T:C→E是两个非扩张非自映象.本文证明了,在一定条件下,由(1.1)式定义的序列{xn}分别弱和强收敛于S,T的公共不动点.本文结果也推广和改进了最近一些人的最新结果.
【Abstract】 Let E be a real uniformly convex Banach space and C a nonempty closed convex subset of E which is also a nonexpansive retract of E.Let S,T:C→E be two nonexpansive mappings.It is shown that under some suitable conditions, the sequence {x_n} defined by(1.1) converges weakly and strongly to some common fixed point of S,T,respectively.The results presented in this paper also extend and improve some recent results.
