Abstract

A nonlinear elastic chain in an external periodic double-barrier potential (a generalized Frenkel-Kontorova model) is considered. Small-amplitude dynamical localized excitations whose parameters lie in and near the gap of the spectrum of linear waves - gap and near-gap solitons - are investigated.
