Convergence Theorems for $G$-Nonexpansive Mappings in CAT(0) Spaces Endowed with Graphs

Watcharapong Anakkamatee, Buris Tongnoi


In this paper, we introduce the concept of a CAT(0) space endowed with a graph. Browder's convergence theorem and Halpern iteration process for $G$-nonexpansive mappings in an underlying space will be presented. This result extends and generalizes the result of  Tiammee, Kaewkhao and Suantai (2015).
