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.

On the Newton-Kantorovich method inK-normed spaces

Rendiconti del Circolo Matematico di Palermo, 2000
The nonlinear operator equation \( f(x) + g(x) = 0 \) in \(K\)-normed spaces is analysed, where \(f\) is differentiable but \(g\) is not. Here \(K\) is a closed convex regular cone in a real Banach space. Under reasonable assumptions, esp. \(f'\) and \(g\) being Lipschitz in some ball, the authors prove solvability by means of the convergence of a ...

Estimates of Majorizing Sequences in the Newton–Kantorovich Method

Numerical Functional Analysis and Optimization, 2006
Let f:B(x 0,R) ⊆ X → Y be an operator, with X and Y Banach spaces, and f′ be Holder continuous with exponent θ. The convergence of the sequence of Newton–Kantorovich approximations is a classical tool to solve the equation f(x) = 0. The convergence of x n is often reduced to the study of the majorizing sequence r n defined by with a, b, k parameters ...

On q-Newton–Kantorovich method for solving systems of equations

Applied Mathematics and Computation, 2005
It is well known that the classical Newton-Kantorovich method, Halley's method and many others in the class of methods devoted to solving a nonlinear equation \(F(x)=0\), are obtained by considering a corresponding truncated Taylor expansion of \(F\). This happens in the framework of the usual calculus. In the paper under review, by using the so called
