Rates of asymptotic regularity for the alternating Halpern-Mann iteration

Optimization and Control 2023-02-28 v2

Abstract

In this paper we extend to UCWUCW-hyperbolic spaces the quantitative asymptotic regularity results for the alternating Halpern-Mann iteration obtained by Dinis and the second author for CAT(0) spaces. These results are new even for uniformly convex normed spaces. Furthermore, for a particular choice of the parameter sequences, we compute linear rates of asymptotic regularity in WW-hyperbolic spaces and quadratic rates of TT- and UU-asymptotic regularity in CAT(0) spaces.
