Integrability of Differential-Difference Equations with Discrete Kinks
C. Scimiterna, D. Levi
In this article we discuss a series of models introduced by Barashenkov, Oxtoby and Pelinovsky to describe some discrete approximations to the ϕ^4 theory which preserve travelling…

C-Integrability Test for Discrete Equations via Multiple Scale Expansions
Christian Scimiterna, Decio Levi
In this paper we are extending the well known integrability theorems obtained by multiple scale techniques to the case of linearizable difference equations. As an example we apply…
