Furthermore, we apply proof mining techniques to get effective rates of asymptotic regularity for Ishikawa iterations of nonexpansive self-mappings of closed convex subsets in $UCW$-hyperbolic spaces. These effective results are new even for uniformly convex Banach spaces.Functional AnalysisLogic47H10; 47H09; 03F10Nonexpansive iterations in uniformly convex $W$-hyperbolic spacestext
