Convergence Theorems for $G$-Nonexpansive Mappings in CAT(0) Spaces Endowed with Graphs
Buris Tongnoi, Watcharapong Anakkamatee · Thai Journal of Mathematics · 2019
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).
