Relaxed Halpern type iteration schemes for sequences of nonexpansive mappings in CAT(0) spaces
Wei-Qi Deng · Topological Methods in Nonlinear Analysis · 2016
Under weaker conditions on parameters, we prove strong convergence theorems of Halpern type iteration schemes for sequences of nonexpansive mappings in CAT(0) spaces. Since there is no assumption of the AKTT-condition imposed on the involved mappings, the results improve those of the authors with related researches.
