Convergence theorems for common fixed points of a sequence of nonexpansive nonself mappings in CAT(0) spaces
Shanguang Qian, Wei-Qi Deng · Studia Scientiarum Mathematicarum Hungarica · 2017
Based on an original idea, i.e., a special way of choosing the indexes of the involved mappings, we propose a new iterative algorithm for approximating common fixed points of a sequence of nonexpansive nonself mappings, and some convergence theorems are established in the framework of CAT(0) spaces. Our results extend the previous results restricted to the situation of a single mapping.
