Expanding the Applicability of Stirling’s Method under Weaker Conditions and Restricted Convergence Regions

open access: yesAnnals of the West University of Timisoara: Mathematics and Computer Science, 2018
In this paper we have provided sufficient conditions to study semilocal and local convergence of the Stirling’s method. The method is used to find fixed points of nonlinear operator equation.

On the Existence of Solutions of Nonlinear Fredholm Integral Equations from Kantorovich’s Technique [PDF]

open access: yesAlgorithms, 2017
The well-known Kantorovich technique based on majorizing sequences is used to analyse the convergence of Newton’s method when it is used to solve nonlinear Fredholm integral equations. In addition, we obtain information about the domains of existence and

Sequences of resource monotones from modular Hamiltonian polynomials [PDF]

open access: yesPhysical Review Research, 2023
We introduce two infinite sequences of entanglement monotones, which are constructed from expectation values of polynomials in the modular Hamiltonian.

Newton's method in Riemannian manifolds

open access: yesJournal of Numerical Analysis and Approximation Theory, 2008
Using more precise majorizing sequences than before [1], [8], and under the same computational cost, we provide a finer semilocal convergence analysis of Newton's method in Riemannian manifolds with the following advantages: larger convergence domain ...

Enhancing Equation Solving: Extending the Applicability of Steffensen-Type Methods

open access: yesMathematics, 2023
Local convergence analysis is mostly carried out using the Taylor series expansion approach, which requires the utilization of high-order derivatives, not iterative methods.

Unified Convergence Criteria of Derivative-Free Iterative Methods for Solving Nonlinear Equations

open access: yesComputation, 2023
A local and semi-local convergence is developed of a class of iterative methods without derivatives for solving nonlinear Banach space valued operator equations under the classical Lipschitz conditions for first-order divided differences.

An improved semilocal convergence analysis for the midpoint method

open access: yesJournal of Numerical Analysis and Approximation Theory, 2016
We expand the applicability of the midpoint method for approximating a locally unique solution of nonlinear equations in a Banach space setting. Our majorizing sequences are finer than the known results in scientific literature [1,3,4,5,6,7,8,9,10,11,19,

Expanding the applicability of Newton-Tikhonov method for ill-posed equations

open access: yesJournal of Numerical Analysis and Approximation Theory, 2014
We present a new semilocal convergence analysis of Newton- Tikhonov methods for solving ill-posed operator equations in a Hilbert space setting. Using more precise majorizing sequences and under the same computational cost as in earlier studies such as [

Extending the Domain with Application of Four-Step Nonlinear Scheme with Average Lipschitz Conditions

open access: yesMathematics, 2023
A novel local and semi-local convergence theorem for the four-step nonlinear scheme is presented. Earlier studies on local convergence were conducted without particular assumption on Lipschitz constant.

On the Convergence Order of Jarratt-Type Methods for Nonlinear Equations

open access: yesAxioms
The order of convergence for Jarratt-type methods in solving nonlinear equations is determined without relying on Taylor expansion. Unlike previous studies, we depend solely on assumptions about the derivatives of the involved operator up to the second ...
