| Abstract: | In convex spaces,this paper introduces a generalized asymptotically quasi-nonexpansive type mapping- a class of mapping,which is more general than asymptotic quasi-nonexpansive type mapping and give some necessary and sufficient conditions for the Ishikawa iterative sequence to converge to a fixed point of generalized asymptotically quasi-nonexpansive type mapping in convex metric spaces. |
