关 键 词:赋范空间  渐近伪压缩映象  不动点  迭代逼近  渐近伪压缩映象  误差项  Ishikawa迭代  Mann迭代  强收敛

Abstract:Let X be a normed linear space, D be a nonempty subset of X and T∶D→X be a uniformly L-Lipschitz asymptotically pseudo-contractive mapping. F(T) denotes the set of all fixed points of T and F(T) is nonempty. Under some suitable assumptions on the iteration parameters {αn} and {βn}, we have proved that the modified Ishikawa and Mann iterative processes with errors for T converge strongly to the fixed point q of T. Several related results deal with iterative approximation problem of fixed point of asymptotically nonexpansive mappings in normed linear space. The results presented in this paper improve and extend those corresponding ones by Chang, Park and Cho, Geobel and Kirk, Liu and Schu and others.
Keywords:asymptotically nonexpansive mapping  asymptotically pseudo-contractive mapping  modified Ishikawa iterative sequence with error  modified Mann iterative sequence with error  normed linear space
