Mohammad Eslamian, Sompong Dhompongsa · 2013
In this paper, we introduce modied Ishikawa iteration process for two nonexpansive semigroups in CAT(0) spaces. Then, we prove strong and △-convergence theorems for such iterative process in CAT(0) spaces. Moreover, we present △-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.
