Soliton solutions of the classical lattice sine-Gordon system
arXiv:hep-th/9502022
Abstract
We study the soliton-type solutions of the system introduced by B. Feigin and the author in in [EF]. We show that it reduces to a top-like system, and we study the behaviour of the solutions at the lattice infinity. We compute the scattering of the solitons and study some periodic solutions of the system.
