    Expanding the convergence domain for Chun-Stanica-Neta family of third order methods in banach spaces 

    Argyros, Ioannis K; Santhosh, George; Magreñán, Á. Alberto (Journal of the Korean Mathematical Society, 2015-01)
    We present a semilocal convergence analysis of a third order method for approximating a locally unique solution of an equation in a Banach space setting. Recently, this method was studied by Chun, Stanica. and Neta. These ...

    Expanding the aplicability of secant method with applications 

    Magreñán, Á. Alberto ; Argyros, Ioannis K (Bulletin of the Korean Mathematical Society, 2015-05)
    We present new sufficient convergence criteria for the convergence of the secant-method to a locally unique solution of a nonlinear equation in a Banach space. Our idea uses Lipschitz and center Lipschitz instead of just ...

    A unified convergence analysis for secant-type methods 

    Argyros, Ioannis K; Magreñán, Á. Alberto (Journal of the Korean Mathematical Society, 2014-11)
    We present a unified local and semilocal convergence analysis for secant-type methods in order to approximate a locally unique solution of a nonlinear equation in a Banach space setting. Our analysis includes he computation ...

    Relaxed secant-type methods 

    Argyros, Ioannis K; Magreñán, Á. Alberto (Nonlinear Studies, 2014-06)
    We present a unified local and semilocal convergence analysis for secant-type methods in order to approximate a locally unique solution of a nonlinear equation in a Banach space setting. Our analysis includes the computation ...

    Different methods for solving STEM problems 

    Argyros, Ioannis K; Magreñán, Á. Alberto; Orcos, Lara ; Sarría, Íñigo ; Sicilia, Juan Antonio (Journal of Mathematical Chemistry, 2019-05)
    We first present a local convergence analysis for some families of fourth and six order methods in order to approximate a locally unique solution of a nonlinear equation in a Banach space setting. Earlier studies have used ...

    Advances in the Semilocal Convergence of Newton's Method with Real-World Applications 

    Argyros, Ioannis K; Magreñán, Á. Alberto; Orcos, Lara; Sarría, Íñigo (Mathematics, 2019-03-24)
    The aim of this paper is to present a new semi-local convergence analysis for Newton's method in a Banach space setting. The novelty of this paper is that by using more precise Lipschitz constants than in earlier studies ...

    Extending the Applicability of Stirling's Method 

    Amorós, Cristina ; Argyros, Ioannis K; Magreñán, Á. Alberto; Regmi, Samundra; González-Crespo, Rubén ; Sicilia, Juan Antonio (Mathematics, 2020-01)
    Stirling's method is considered as an alternative to Newton's method when the latter fails to converge to a solution of a nonlinear equation. Both methods converge quadratically under similar convergence criteria and require ...

    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 ...
