Common Fixed Points of Generalized Quasi--Contractive Type Operators By a Three-Step Iterative Process in CAT(0) Spaces

Abstract

The aim of this paper is to approximate common fixed points of a recent three step iterative process essentially due to Thakur et al [16] for two generalized quasi--contractive type operators and establish strong convergence result for the same operators in $CAT(0)$ spaces. The results obtained in this paper extend and improve the recent ones announced by Saluja [15], Xu and Noor [17], Noor [13], Picard [14], Mann [12], Ishikawa [10] and many others.
