✦ Synopsis
We introduce a new two-step method to approximate a solution of a nonlinear operator equation in a Banach space. An existence-uniqueness theorem and error estimates are provided for this iteration using Newton-Kantorovich-type assumptions and a technique based on a new system of recurrence relations. For a special choice of the parameter involved we use, our method is of fourth order.

We provide sufficient conditions for the convergence of inexact Newton methods to a solution of a nonlinear equation in a Banach space. Earlier results have used conditions on the first Fr&het-derivative. Our results differ from earlier results in that we use Lipschitz conditions on the second Fr&~h
Problems relating to the analysis of instability and asymptotic stability are considered for non-steady systems of ordinary differential equations, solved for the derivative. It is assumed that the right-hand sides of the system converge uniformly as the time increases without limit, tending to cert
