Multiple-scale analysis of discrete nonlinear partial difference equations: the reduction of the lattice potential KdV

Exactly Solvable and Integrable Systems 2009-11-11 v1

Abstract

We consider multiple lattices and functions defined on them. We introduce slow varying conditions for functions defined on the lattice and express the variation of a function in terms of an asymptotic expansion with respect to the slow varying lattices. We use these results to perform the multiple--scale reduction of the lattice potential Korteweg--de Vries equation.
