A GENERALIZED THEOREM OF MIRANDA AND THE THEOREM OF NEWTON–KANTOROVICH

Numerical Functional Analysis and Optimization, 2002
ABSTRACT In this paper, we discuss the theorems of Newton–Kantorovich, the Theorem of Miranda, and the relationship between them. We begin by generalizing Miranda's theorem and propose a converse. Then we show that mappings satisfying the assumptions of the Theorem of Newton–Kantorovich in a strong sense automatically satisfy those of our ...

A Newton–Kantorovich convergence theorem for the inverse-free Jarratt method in Banach space

Applied Mathematics and Computation, 2006
Under weak conditions, we establish a Newton-Kantorovich type convergence theorem of the inverse-free Jarratt method in Banach space which is used to solve a nonlinear operator equation. Finally, some examples are provided to show the applicability of our theorem.

A note on the Kantorovich theorem for Newton iteration

open access: yesJournal of Computational and Applied Mathematics, 1993
In this paper, a new theorem for the Newton method convergence is obtained. Its condition is different from that of the Kantorovich theorem and therefore it has theoretical and practical ...

A robust Kantorovich’s theorem on the inexact Newton method with relative residual error tolerance

open access: yesJournal of Complexity, 2012
We prove that under semi-local assumptions, the inexact Newton method with a fixed relative residual error tolerance converges Q-linearly to a zero of the nonlinear operator under consideration.

The Newton-Kantorovich Theorem

2020
Solving nonlinear equations is one of the mathematical problems that is frequently encountered in diverse scientific disciplines. Thus, with the notation $$\displaystyle f(x)=0, $$ we include the problem of finding unknown quantity x, which can be a real or complex number, a vector, a function, etc., from data provided by the function f, which ...

A Modification of the Lipschitz Condition in the Newton–Kantorovich Theorem

Zeitschrift für Analysis und ihre Anwendungen, 2016
We analyse the semilocal convergence of Newton’s method in Banach spaces under a modification of the classic Lipschitz condition on the first derivative of the operator involved in Kantorovich’s theory. For this, we use a technique based on recurrence relations instead of the well-known majorant principle of Kantorovich.
