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. (C) 2001 American Institute of Physics.},
