On the stability of some fixed point procedures.(English)Zbl 1031.47030

Summary: Following the concept of $$T$$-stability defined by us [“Generalized contractions and applications” (Romanian) (Colectia Universitaria, Editura Cub Press 22, Baia Mare) (1997; Zbl 0885.47022)] for a fixed point iteration procedure, we establish in a simpler manner the same stability results for the Picard iteration and Mann iteration considered in metric spaces and normed linear spaces, respectively.
