摘    要:Under the framework of uniformly smooth Banach spaces, Chang proved in 2006 that the sequence {xn} generated by the iteration xn+1 =αn+1f(xn) + (1 - αn+1)Tn+1xn converges strongly to a common fixed point of a finite family of nonexpansive maps {Tn}, where f : C → C is a contraction. However, in this paper, the author considers the iteration in more general case that {Tn} 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.

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.
Keywords:infinitely many nonexpansive mappings  contractive mapping  weakly sequential continuity
