Ishikawa iteration process with errors for nonexpansive mappings in uniformly convex Banach spaces
Deng Lei, Shenghong Li · International Journal of Mathematics and Mathematical Sciences · 2000
We shall consider the behaviour of Ishikawa iteration with errors in a uniformly convex Banach space. Then we generalize the two theorems of Tan and Xu without the restrictions that C is bounded and limsupnsn < 1.
