On stability results for φφ-strongly pseudocontractive mappings

We study the stability problems of the following unified iterative scheme involving a φφ-strongly pseudocontractive mapping (or φφ-hemicontractive mapping) TTxn+1=f(T,vn,xn)=αnxn+βnTvn+γnunxn+1=f(T,vn,xn)=αnxn+βnTvn+γnunin arbitrary Banach spaces. We apply our results to obtain stability of an iterative scheme for a family of kk-selfmappings.
