# Local convergence of some Newton type methods for nonlinear systems

## Abstract

In order to approximate the solutions of nonlinear systems $F(x)=0,$ with $$F:D\subseteq {\mathbb R}^n \rightarrow {\mathbb R}^n$$, $$n\in {\mathbb N}$$, we consider the method

\begin{align*} x_{k+1} & =x_{k}-A_{k}F(x_{k})\\A_{k+1} & =A_{k}\big(2I-F^{\prime}(x_{k+1}\big)A_{k}),\;k=0,1,…, \,A_{0}\in M_{n}({\Bbb R}), x_0 \in D,\end{align*} and we study its local convergence.

## Keywords
