摘要
设X为具有Opial条件的一致凸Banach空间 ,C为X的非空有界闭凸子集 ,T ,S为C到自身的 2个渐近非扩张映射且T和S有公共的不动点 .本文主要考察了一种带误差的迭代逼近T和S有公共的不动点 ,在迭代参数 {an},{bn},{cn},{a′n},{b′n},{c′n}的适当假设下 ,证明了所构造的带误差的迭代序列弱收敛于T和S的某个公共不动点 。
Let X be a uniform Banach space satisfying Opial condition and C a nonempty bounded closed convex subset of X . Let T, S be two asymptotically nonexpansive mappings on C with F(T)∩F(S)≠ . This paper deals with approximating common fixed point of T and S through an iterative sequence with errors. Under some suitable assumptions on the iteration parameters {a n}, {b n}, {c n}, {a′ n}, {b′ n} , an d {c′ n}, we have proved that the iterative sequence with errors converges weakly to some common fixed point of T and S . We also investigate the strong convergence of such iterative sequence.
