摘要:

该文首先在一般Banach空间中对渐近非扩张型半群证明了两个不动点存在定理, 并由此给出了渐近非扩张型半群Mann型迭代 序列的强收敛定理. 该文的主要结果将Suzuki和Takahashi 的相应结果推广到non-Lipschitzian半群情形.

关键词: 不动点, 渐近非扩张型半群, Mann型序列, 强收敛定理

Abstract:

This paper is first devoted to proving two existence theorems of fixed points  for  asymptotically nonexpansive type semigroups in general Banach  spaces. Based on these results, a strong convergence theorem of Mann's type sequences for the asymptotically nonexpansive type semigroups is given. The main results extend the
results of Suzuki and Takahashi  to the case of  the non-Lipschitzian  semigroups.

Key words: Fixed , point, Asymptotically nonexpansive type semigroup,  Mann's type sequences, Strong convergence theorem
