Abstract :

We study the method considered in Xiao and Yin (2015), for solving systems of nonlinear equations, modified suitably to include the nonlinear equations in Banach spaces. The novelty of this study lies in the fact that our conditions are weaker than the conditions used in earlier studies. This way we extend the applicability of the method. Numerical examples are also given in this study where earlier results cannot apply to solve equations but our results can apply.

Keywords :

Newton-type method, radius of convergence, local convergence, restricted convergence domains.
