Kantorovich's theorem on Newton's method for solving strongly regular generalized equation

Abstract

In this paper we consider the Newton's method for solving the generalized equation of the form $f(x)+F(x)\ni 0,$ where $f:\Omega \to Y$ is a continuously differentiable mapping, $X$ and $Y$ are Banach spaces, $\Omega \subseteq X$ an open set and $F:X\rightrightarrows Y$ be a set-valued mapping with nonempty closed graph. We show that, under strong regularity of the generalized equation, concept introduced by S.M.Robinson in [27], and starting point satisfying the Kantorovich's assumptions, the Newton's method is quadratically convergent to a solution, which is unique in a suitable neighborhood of the starting point. The analysis presented based on Banach Perturbation Lemma for generalized equation and the majorant technique, allow to unify some results pertaining the Newton's method theory.
