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
