Some Convergence Theorems for Contractive Type Mappings inCAT(0) Spaces
Kyung Soo Kim · Abstract and Applied Analysis · 2013
We establish theorems of strong convergence, for the Ishikawa-type (or two step;cf. Ishikawa, 1974) iteration scheme, to a fixed point of a uniformlyL-Lipschitzian asymptotically demicontractive mapping and a uniformlyL-Lipschitzian hemicontractive mapping inCAT(0) space. Moreover, we will propose some open problems.
