Modified Ishikawa iteration process for two nonexpansive semigroups in CAT(0) spacess

In this paper, we introduce modified Ishikawa iteration process for two nonexpansive semigroups in CAT(0) spaces. Then, we prove strong and Δ-convergence theorems for such iterative process in CAT(0) spaces. Moreover, we present Δ-convergence theorems of Ishikawa iteration process for a family of no...

Description
Summary:In this paper, we introduce modified Ishikawa iteration process for two nonexpansive semigroups in CAT(0) spaces. Then, we prove strong and Δ-convergence theorems for such iterative process in CAT(0) spaces. Moreover, we present Δ-convergence theorems of Ishikawa iteration process for a family of nonexpansive mappings in CAT(0) spaces. The results obtained in this paper extend and improve some recent known results.
