Approximating fixed points of λ-firmly nonexpansive mappings in Banach spaces

Abstract

We study the convergence of the Ishikawa iteration methods to fixed points for the result of Smarzewski (1991). Our theorems also improve recent theorems due to Sharma and Sahu (1996).

Keywords

• λ-firmly nonexpansive mapping
• fixed point
• Opial's condition
• Fréchet differentiable norm.
