We present a modification of the Newton—Kantorovich method for nonlinear operator equations in a Banach space. We prove, under certain conditions, that this modified Newton—Kantorovich method has quadratic convergence. The modified Newton—Kantorovich method is used to solve some nonlinear integral and integral- differential equations.

Keywords: Banach space, modification of the Newton—Kantorovich method, nonlinear operator equations, quadratic convergence
