Recurrent Inequalities and Some of their Applications to Picard and Mann Iterations
Berinde Vasile, Măruşter Ştefan · Annals of West University of Timisoara - Mathematics and Computer Science · 2014
Abstract Two lemmas concerning the superior bound of a numerical sequence satisfying a common recurrence inequality are given. As applications, the error estimations are obtained for the Picard and Mann iterations in the case of demicontractive mappings. Additional conditions that ensure the strong convergence in the same cases can be obtained on the basis of these lemmas.
