We present a new technique to improve the convergence domain for Newton’s method both in the semilocal and local case. It turns out that with the new technique the sufficient convergence conditions for Newton’s method are weaker, the error bounds are tighter and the information on the location of the solution is at least as precise as in earlier studies. Numerical examples are given showing that our results apply to solve nonlinear equations in cases where the old results cannot apply.

Argyros, Ioannis K; Magreñán, Á. Alberto (UNIR); Orcos, Lara (UNIR); Sicilia, Juan Antonio (UNIR) (Journal of Mathematical Chemistry, 08/2017)We present a local convergence analysis for a relaxed two-step Newton-like method. We use this method to approximate a solution of a nonlinear equation in a Banach space setting. Hypotheses on the first Fr,chet derivative ...
Magreñán, Á. Alberto (UNIR); Argyros, Ioannis K; Sicilia, Juan Antonio (UNIR) (Journal of Mathematical Chemistry, 08/2017)We present a new semilocal convergence analysis for Newton-like methods using restricted convergence domains in a Banach space setting. The main goal of this study is to expand the applicability of these methods in cases ...
Decision model for siting transport and logistic facilities in urban environments: A methodological approach Frailea, Alberto; Larrodé, Emilio; Magreñán, Á. Alberto (UNIR); Sicilia, Juan Antonio (UNIR) (Journal of Computational and Applied Mathematics, 01/2016)In this study, based on the use of a geographic information system (GIS), we define a decision model for determining the possible optimal locations of various facilities in an urban setting, which can be used by the transport ...
