Abstract: |
Under the framework of uniformly smooth Banach spaces, Chang$^{[1]}$ proved in 2006 that the sequence $\{x_n\}$ generated by the iteration $x_{n 1}= \alpha_{n 1}f(x_n) (1-\alpha_{n 1})T_{n 1}x_n$ converges strongly to a common fixed point of a finite family of nonexpansive maps $\{T_n\}$, where $f: C\to C$ is a contraction. However, in this paper, the author considers the iteration in more general case that $\{T_n\}$ is an infinite family of nonexpansive maps, and proves that Chang's result holds still in the setting of reflexive Banach spaces with the weakly sequentially continuous duality mapping. |
