On Newton-type Methods with Cubic Convergence [PDF]

open access: yes, 2005
Recently, there has been some progress on Newton-type methods with cubic convergence that do not require the computation of second derivatives. Weerakoon and Fernando (Appl. Math. Lett.

On Newton-type methods for multiple roots with cubic convergence [PDF]

open access: yes, 2009
We introduce two families of Newton-type methods for multiple roots with cubic convergence. A further Newton-type method for multiple roots with cubic convergence is presented that is related to quadrature.

Newton-Type Methods on Generalized Banach Spaces and Applications in Fractional Calculus

open access: yesAlgorithms, 2015
We present a semilocal convergence study of Newton-type methods on a generalized Banach space setting to approximate a locally unique zero of an operator. Earlier studies require that the operator involved is Fréchet differentiable.

Inexact Newton-Kantorovich Methods for Constrained Nonlinear Model Predictive Control

open access: yes, 2018
In this paper we consider Newton-Kantorovich type methods for solving control-constrained optimal control problems that appear in model predictive control. Conditions for convergence are established for an inexact version of the Newton-Kantorovich method

Asymptotically Newton-Type Methods without Inverses for Solving Equations

open access: yesMathematics
The implementation of Newton’s method for solving nonlinear equations in abstract domains requires the inversion of a linear operator at each step. Such an inversion may be computationally very expensive or impossible to find.

Local convergence of some Newton-type methods for nonlinear systems

open access: yesJournal of Numerical Analysis and Approximation Theory, 2004
In order to approximate the solutions of nonlinear systems\[F(x)=0,\]with \(F:D\subseteq {\mathbb R}^{n}\rightarrow {\mathbb R}^{n}\),\(n\in {\Bbb N}\), we consider the method\begin{align*}x_{k+1} & =x_{k}-A_{k}F(x_{k})\label{f1.4}\\A_{k+1} & =A_{k}(2I-F^
