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