Strong convergence of an Ishikawa-type algorithm in CAT ( 0 ) spaces
Hafiz Fukhar-ud-din · Fixed Point Theory and Applications · 2013
We study strong convergence of an Ishikawa-type algorithm of two asymptotically nonexpansive type maps to their common fixed point on a space. Our work provides an affirmative answer to the question of Tan and Xu (Proc. Am. Math. Soc. 122:733-739, 1994); in particular, strong convergence of an Ishikawa-type algorithm of two asymptotically nonexpansive maps without the rate of convergence condition is obtained on a nonlinear domain.
