Cover Story: A plethora of problems from many disciplines can be reduced to solving nonlinear Banach space-valued equations. Most solution methods are of an iterative nature since closed-form solutions are possible only in special cases. We study the semi-local convergence of a three-step Newton-type method for solving nonlinear equations under the classical Lipschitz conditions for first-order derivatives. Earlier studies have used convergence analysis requiring the existence of the sixth derivative not appearing on the method, hence restricting the applicability of the method to operators which are at least six times differentiable. View this paper.
