Newton's method and regularly smooth operators

open access: yesJournal of Numerical Analysis and Approximation Theory, 2011
A semilocal convergence analysis for Newton's method in a Banach space setting is provided in this study. Using a combination of regularly smooth and center regularly smooth conditions on the operator involved, we obtain more precise majorizing sequences

On Newton's method for subanalytic equations

open access: yesJournal of Numerical Analysis and Approximation Theory, 2017
We present local and semilocal convergence results for Newton’s method in order to approximate solutions of subanalytic equations. The local convergence results are given under weaker conditions than in earlier studies such as [9], [10], [14], [15], [24]

Fractional Newton-Raphson Method

open access: yesApplied Mathematics and Sciences An International Journal (MathSJ), 2021
The Newton-Raphson (N-R) method is useful to find the roots of a polynomial of degree n, with n ∈ N. However, this method is limited since it diverges for the case in which polynomials only have complex roots if a real initial condition is taken. In the present work, we explain an iterative method that is created using the fractional calculus, which we

Transforming common-sense beliefs into Newtonian thinking through Just-In-Time Teaching

open access: yesPhysical Review Special Topics. Physics Education Research, 2010
To determine whether teaching an introductory physics course with a traditional lecture style or with Just-in-Time teaching (a student-centered, interactive-engagement style) will help students to better understand Newtonian concepts, such as Newton’s ...

Newton-Product Integration for a Stefan Problem with Kinetics [PDF]

open access: yesJournal of Sciences, Islamic Republic of Iran, 2011
Stefan problem with kinetics is reduced to a system of nonlinear Volterra integral equations of second kind and Newton's method is applied to linearize it. Product integration solution of the linear form is found and sufficient conditions for convergence

Approximating solutions of equations using Newton's method with a modified Newton's method iterate as a starting point

open access: yesJournal of Numerical Analysis and Approximation Theory, 2007
In this study we are concerned with the problem of approximating a locally unique solution of an equation in a Banach space setting using Newton's and modified Newton's methods. We provide weaker convergence conditions for both methods than before [6]-[8]

Generalized Newton's Method based on Graphical Derivatives [PDF]

open access: yes, 2010
This paper concerns developing a numerical method of the Newton type to solve systems of nonlinear equations described by nonsmooth continuous functions. We propose and justify a new generalized Newton algorithm based on graphical derivatives, which have

Newton's method in the context of gradients

open access: yesElectronic Journal of Differential Equations, 2007
This paper gives a common theoretical treatment for gradient and Newton type methods for general classes of problems. First, for Euler-Lagrange equations Newton's method is characterized as an (asymptotically) optimal variable steepest descent method ...

Improving Newton's method performance by parametrization: the case of Richards equation [PDF]

open access: yes, 2016
The nonlinear systems obtained by discretizing degenerate parabolic equations may be hard to solve, especially with Newton's method. In this paper, we apply to Richards equation a strategy that consists in defining a new primary unknown for the ...

Numerical Analysis of Time-Accurate Solution of Nonlinear Flow Models by Implicit Finite Differences

open access: yesNonlinear Analysis, 2003
Implicit finite differences are often applied to solve flow models. A standard technique to solve these equations is Newton's method. lf time step is too large although the difference equation could be computationally stable, Newton's method may fail ...
