Moudafi’s viscosity approximations with Meir–Keeler contractions. (English) Zbl 1111.47059

The author discusses Moudafi’s viscosity approximations with Meir–Keeler contractions. First, he presents very simple proofs of Xu’s theorems concerning Moudafi’s approximations. Next, he proves that Browder’s and Halpern’s type convergence theorems imply Moudafi’s viscosity approximations. With these foregoing results, he states several new theorems.
