S ep 1 99 7 Perturbation analysis of weakly discrete kinks
We present a perturbation theory of kink solutions of discrete Klein-Gordon chains. The un-perturbed solutions correspond to the kinks of the adjoint partial differential equation. The perturbation theory is based on a reformulation of the discrete chain problem into a partial differential equation with spatially modulated mass density. The first order corrections to the kink solutions are obta...
متن کاملTopological discrete kinks
A spatially discrete version of the general kink-bearing nonlinear Klein-Gordon model in (1 + 1) dimensions is constructed which preserves the topological lower bound on kink energy. It is proved that, provided the lattice spacing h is sufficiently small, there exist static kink solutions attaining this lower bound centred anywhere relative to the spatial lattice. Hence there is no Peierls-Naba...

A spatially discrete version of the general kink-bearing nonlinear Klein-Gordon model in (1 + 1) dimensions is constructed which preserves the topological lower bound on kink energy. It is proved that, provided the lattice spacing h is suuciently small, there exist static kink solutions attaining this lower bound centred anywhere relative to the spatial lattice. Hence there is no Peierls-Nabarr...
متن کاملPerturbation analysis of the discrete Riccati equation
The sensitivity of the discrete-time matrix Riccati equation relative to perturbations in its coefficients is studied. Both local and non-local perturbation bounds are obtained. In particular the conditioning of the equation is determined.
متن کاملTravelling kinks in discrete φ 4 models
In recent years, three exceptional discretizations of the φ 4 model have been discovered [S97, BT97, K03] which support translationally invariant kinks, i.e., families of stationary kinks centered at arbitrary points between the lattice sites. We address the question of the persistence of these kinks for nonzero velocity. By computing the Stokes constants in beyond-all-order asymptotic expansio...
