摘要 在一致凸光滑的Banach空间框架下,利用度量投影,对一个有限簇渐进非扩张映射引入了新的混合投影迭代程序,证明了该迭代程序强收敛于该有限簇渐进非扩张映射的一个公共不动点,推广和改进了Dehghan的主要结果. A strong convergence theorem for a family of asymptotically nonexpansive mappings is obtained in a uniformly convex and smooth Banach space.The results extend and improve the corresponding results of Dehghan.
