    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 ...

    Ball convergence of a sixth-order Newton-like method based on means under weak conditions 

    Magreñán, Á. Alberto ; Argyros, Ioannis K; Rainer, J Javier ; Sicilia, Juan Antonio (Journal of Mathematical Chemistry, 2018-08)
    We study the local convergence of a Newton-like method of convergence order six to approximate a locally unique solution of a nonlinear equation. Earlier studies show convergence under hypotheses on the seventh derivative ...

    Extended local convergence for some inexact methods with applications 

    Argyros, Ioannis K; Legaz, M. J.; Magreñán, Á. Alberto; Moreno, D.; Sicilia, Juan Antonio (Journal of Mathematical Chemistry, 2019-05)
    We present local convergence results for inexact iterative procedures of high convergence order in a normed space in order to approximate a locally unique solution. The hypotheses involve only Lipschitz conditions on the ...

    Unified local convergence for newton's method and uniqueness of the solution of equations under generalized conditions in a Banach space 

    Argyros, Ioannis K; Magreñán, Á. Alberto; Orcos, Lara ; Sarría, Íñigo (Mathematics, 2019-05)
    Under the hypotheses that a function and its Frechet derivative satisfy some generalized Newton-Mysovskii conditions, precise estimates on the radii of the convergence balls of Newton's method, and of the uniqueness ball ...

    Study of local convergence and dynamics of a king-like two-step method with applications 

    Argyros, Ioannis K; Magreñán, Á. Alberto; Moysi, Alejandro; Sarría, Íñigo ; Sicilia, Juan Antonio (Mathematics, 2020-07-01)
    In this paper, we present the local results of the convergence of the two-step King-like method to approximate the solution of nonlinear equations. In this study, we only apply conditions to the first derivative, because ...

    Local convergence and a chemical application of derivative free root finding methods with one parameter based on interpolation 

    Argyros, Ioannis K; Magreñán, Á. Alberto ; Orcos, Lara (Journal of Mathematical Chemistry, 2016-08)
    We present a local convergence analysis of a derivative free fourth order method with one parameter based on rational interpolation in order to approximate a locally unique root of a function. The method is optimal in the ...

    Local Convergence and the Dynamics of a Two-Step Newton-Like Method 

    Argyros, Ioannis K; Magreñán, Á. Alberto (International Journal of Bifurcation and Chaos in Applied Sciences and Engineering, 2016-05)
    We present the local convergence analysis and the study of the dynamics of a two-step Newton-like method in order to approximate a locally unique solution of multiplicity one of a nonlinear equation.

    On the local convergence and the dynamics of Chebyshev–Halley methods with six and eight order of convergence 

    Magreñán, Á. Alberto ; Argyros, Ioannis K (Journal of Computational and Applied Mathematics, 2016-05)
    We study the local convergence of Chebyshev–Halley methods with six and eight order of convergence to approximate a locally unique solution of a nonlinear equation. In Sharma (2015) (see Theorem 1, p. 121) the convergence ...

    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 ...

    Local convergence for multi-point-parametric Chebyshev–Halley-type methods of high 

    Argyros, Ioannis K; George, Santhosh; Magreñán, Á. Alberto (Journal of Computational and Applied Mathematics, 2015-07)
    We present a local convergence analysis for general multi-point-Chebyshev-Halley-type methods (MMCHTM) of high convergence order in order to approximate a solution of an equation in a Banach space setting. MMCHTM includes ...
