    Improving the domain of parameters for Newton's method with applications 

    Argyros, Ioannis K; Magreñán, Á. Alberto ; Sicilia, Juan Antonio (Journal of Computational and Applied Mathematics, 2017-07)
    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 ...

    Local convergence of a relaxed two-step Newton like method with applications 

    Argyros, Ioannis K; Magreñán, Á. Alberto ; Orcos, Lara ; Sicilia, Juan Antonio (Journal of Mathematical Chemistry, 2017-08)
    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 ...

    New improved convergence analysis for Newton-like methods with applications 

    Magreñán, Á. Alberto ; Argyros, Ioannis K; Sicilia, Juan Antonio (Journal of Mathematical Chemistry, 2017-08)
    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 ...

    Extending the applicability of the local and semilocal convergence of Newton's method 

    Argyros, Ioannis K; Magreñán, Á. Alberto (Applied Mathematics and Computation, 2017-01)
    We present a local as well a semilocal convergence analysis for Newton's method in a Banach space setting. Using the same Lipschitz constants as in earlier studies, we extend the applicability of Newton's method as follows: ...

    Local convergence and the dynamics of a two-point four parameter Jarratt-like method under weak conditions 

    Amat, Sergio ; Argyros, Ioannis K; Busquier, Sonia; Magreñán, Á. Alberto (Numerical Algorithms, 2017-02)
    We present a local convergence analysis of a two-point four parameter Jarratt-like method of high convergence order in order to approximate a locally unique solution of a nonlinear equation. In contrast to earlier studies ...

    Secant-like methods for solving nonlinear models with applications to chemistry 

    Magreñán, Á. Alberto ; Argyros, Ioannis K; Orcos, Lara (Journal of Mathematical Chemistry, 2017)
    We present a local as well a semilocal convergence analysis of secant-like methods under g eneral conditions in order to approximate a locally unique solution of a nonlinear equation in a Banach space setting. The new ...

    On the convergence of a higher order family of methods and its dynamics 

    Argyros, Ioannis K; Cordero, Alicia; Magreñán, Á. Alberto ; Torregrosa, Juan Ramón (Journal of Computational and Applied Mathematics, 2017-01)
    In this paper, we present the study of the local convergence of a higher-order family of methods. Moreover, the dynamical behavior of this family of iterative methods applied to quadratic polynomials is studied. Some ...

    Improved semilocal convergence analysis in Banach space with applications to chemistry 

    Argyros, Ioannis K; Giménez de Ory, Elena ; Magreñán, Á. Alberto (Journal of Mathematical Chemistry, 2017)
    We present a new semilocal convergence analysis for Secant methods in order to approximate a locally unique solution of a nonlinear equation in a Banach space setting. Our analysis includes the computation of the bounds ...
