Abstract:
We establish weak and strong convergence theorems of modified
Ishikawa iteration with errors with respect to three nonexpansive
mappings. We improve and extend many results due to Khan and
Fukhar-ud-din, Tamura and Takahashi and many authors.
We also point out that an additional condition imposed in Rafiq\'s
paper does not make sense.
