We propose a new approach to the multiple-scale analysis of difference equations, in the context of the finite operator calculus. We derive the transformation formulae that map any given dynamical system, continuous or discrete, into a rescaled discrete system, by generalizing a classical result due to Jordan. Under suitable analytical hypotheses on the function space we consider, the rescaled equations are of finite order. Our results are applied to the study of multiple-scale reductions of… Expand
DISCRETE MULTISCALE ANALYSIS: A BIATOMIC LATTICE SYSTEM
We discuss a discrete approach to the multiscale reductive perturbative method and apply it to a biatomic chain with a nonlinear interaction between the atoms. This system is important to describeExpand
Integrability test of discrete nonlinear Schrödinger equations via multiscale reduction
In this article, we consider the multiscale reduction around the harmonic solution of a general discrete nonlinear Schrödinger equation (dNLSE) depending on constant coefficients. According to theExpand
