摘要
在具有一致Gateaux可微范数的Banach空间中,研究了一个逼近非扩张映射不动点的粘性逼近方法,运用Banach极限推导了该逼近方法收敛的充分条件,并通过对该粘性逼近方法的修正逐步减少了收敛分析中的限制条件.
In this paper, a viscosity approximation scheme is proposed for approximating the fixed point of nonexpansive mappings in a uniformly smooth Banach space, which sufficient condition for strong convergence is deduced with Banach limit. Restriction conditions of convergence are reduced successively based on the modified viscosity approximation method.
