The purpose of this paper is to study the viscosity iterative schemes for approximating
a fixed point of an asymptotically nonexpansive semigroup on a compact convex
subset of a smooth Banach space with respect to a sequence {μi,n}
m,∞
i=1,n=1 of strongly
asymptotic invariant means defined on an appropriate space of bounded real valued
functions of the semigroup. Our results extend and improve the result announced by
Lau et al. (Nonlinear Anal. 67(4):1211-1225, 2007) and many others.
