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

الملخص EN

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.
