Effective results on compositions of nonexpansive mappings

Description

This paper provides uniform bounds on the asymptotic regularity for iterations associated to a finite family of nonexpansive mappings. We obtain our quantitative results in the setting of (r, δ)-convex spaces, a class of geodesic spaces which generalizes metric spaces with a convex geodesic bicombing.
