摘要:利用1个新的迭代格式研究了Banach空间中有限个非扩张映射的公共不动点问题,并给出了其弱收敛定理,推广了由单个算子所产生的Ishikawa迭代序列的弱收敛性结果.

关键词: 非扩张算子, 不动点, 一致凸Banach空间, Opial 条件, Frechet 可微

Abstract: Through using a new iteration scheme,the problem of finding a common fixed point of finite nonexpansive mappings  was considered in a uniformly  convex Banach space,some weak convergence theorems were given,which generalized some weak convergence theorems of the Ishikawa iteration sequence with only one operator.

Key words: nonexpansive mappings, fixed point, uniformly convex Banach spaces, opial condition, Frechet differentiable
