Abstract We establish Δ-convergence results of a sequence generated by the modified S-iteration process for two nonexpansive mappings in complete $\operatorname {CAT}(\kappa)$ CAT ( κ ) spaces. Some numerical examples are also provided to compare with the Ishikawa-type iteration process. Our main result extends the corresponding results in the literature.
