Approximation of Common Fixed Points of Pointwise Asymptotic Nonexpansive Maps in a Hadamard Space
Safeer Hussain Khan, Hafiz Fukhar-ud-din · Advances in Pure Mathematics · 2012
We establish weak and strong convergence of Ishikawa type iterates of two pointwise asymptotic nonexpansive maps in a Hadamard space. For weak and strong convergence results, we drop “rate of convergence condition”, namely (Cn(x)-1)＜ to answer in the affirma-tive to the open question posed by Tan and Xu [1] even in a general setup.
