Some Convergence Theorems for Contractive Type Mappings in CAT(0) Spaces

Abstract

We establish theorems of strong convergence, for the Ishikawa‐type (or two step; cf. Ishikawa, 1974) iteration scheme, to a fixed point of a uniformly L‐Lipschitzian asymptotically demicontractive mapping and a uniformly L‐Lipschitzian hemicontractive mapping in CAT(0) space. Moreover, we will propose some open problems.
