A Unified Local-Semilocal Convergence Analysis of Efficient Higher Order Iterative Methods in Banach Spaces

open access: yesMathematics, 2022
To deal with the estimation of the locally unique solutions of nonlinear systems in Banach spaces, the local as well as semilocal convergence analysis is established for two higher order iterative methods. The given methods do not involve the computation

Semilocal Convergence Domain of a Chandrasekhar Integral Equation

open access: yesSymmetry
In this study, we discuss the semilocal convergence analysis of a fourth-order iterative method in Banach spaces. We assume the Fréchet derivative satisfies the Lipschitz continuity condition, obtains suitable recurrence relations, and determines the domain of convergence under appropriate initial estimates.

A Semilocal Convergence for a Uniparametric Family of Efficient Secant-Like Methods [PDF]

open access: yesJournal of Function Spaces, 2014
We present a semilocal convergence analysis for a uniparametric family of efficient secant-like methods (including the secant and Kurchatov method as special cases) in a Banach space setting (Ezquerro et al., 2000–2012). Using our idea of recurrent functions and tighter majorizing sequences, we provide convergence results under the same or less ...

A new semilocal convergence theorem for Newton's method [PDF]

open access: yesJournal of Computational and Applied Mathematics, 1997
A new semilocal convergence theorem for Newton's method is established for solving a nonlinear equation F(x)=0, defined in Banach spaces. It is assumed that the operator F is twice Fréchet differentiable, and F″ satisfies a Lipschitz type condition. Results on uniqueness of solution and error estimates are also given.

Semilocal Convergence of a Multi-Step Parametric Family of Iterative Methods

open access: yesSymmetry, 2023
In this paper, we deal with a new family of iterative methods for approximating the solution of nonlinear systems for non-differentiable operators. The novelty of this family is that it is a m-step generalization of the Steffensen-type method by updating the divided difference operator in the first two steps but not in the following ones.

Semilocal Convergence for a Fifth-Order Newton's Method Using Recurrence Relations in Banach Spaces [PDF]

open access: yesJournal of Applied Mathematics, 2011
We study a modified Newton's method with fifth-order convergence for nonlinear equations in Banach spaces. We make an attempt to establish the semilocal convergence of this method by using recurrence relations. The recurrence relations for the method are
