We introduce implicit and explicit iterative algorithms for the construction of fixed points of pseudocontractions T in Hilbert spaces. We prove that the proposed iterative algorithms converge strongly to the minimum-norm fixed point of T. Moreover we show that some of the existing iterative algorithms for nonexpansive mappings fail to converge when applied to pseudocontractions.

Abstract

We introduce implicit and explicit iterative algorithms for the construction of fixed points of pseudocontractions T in Hilbert spaces. We prove that the proposed iterative algorithms converge strongly to the minimum-norm fixed point of T. Moreover we show that some of the existing iterative algorithms for nonexpansive mappings fail to converge when applied to pseudocontractions.
