摘要：
A new iterative algorithm for approximating fixed points of mean nonexpansive mappings in CAT(0) spaces is introduced. As a result, a Delta-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.
