Abstract


A new iterative algorithm for approximating fixed points
of mean nonexpansive mappings in CAT(0) spaces is introduced. As a result, a weak convergence theorem is established.
The result we obtain improves and extends several recent results in the literature. Finally, some numerical examples are presented
to illustrate the main result and to compare the new algorithm with some existing ones.
