Effective asymptotic regularity for one-parameter nonexpansive semigroups

We give explicit bounds on the computation of approximate common fixed points of one-parameter strongly continuous semigroups of nonexpansive mappings on a subset C of a general Banach space. Moreover, we provide the first explicit and highly uniform rate of convergence for an iterative procedure to compute such points for convex C. Our results are obtained by a logical analysis of the proof (proof mining) of a theorem by T. Suzuki.
