The equivalence between the Mann and Ishikawa iterations dealing with generalized contractions

10 months ago

Abstract We show that the Mann and Ishikawa iterations are equivalently used to approximate fixed points of generalized contractions. AuthorsS.M.…

The convergence of an implicit mean value iteration

10 months ago

Abstract We show the convergence of an implicit mean value iteration when applied to uniformly pseudocontractive maps. Remarks about other…

The equivalence of Mann and Ishikawa iterations dealing with uniformly pseudocontractive maps without bounded range

10 months ago

Abstract We prove that Mann and Ishikawa iterations are equivalent models dealing with \(\psi\)-uniformly pseudocontractive or d-weakly contractive maps without…
