   abstract = {The energy of the potential relief and of the Peierls barrier for
a topological excitation (kink) in the Frenkel-Kontorova model is
calculated in the continual limit to the second order of perturbation
theory. A new method is proposed for analysis of the problem in a
strongly discrete limit. Analytical results are compared with the
results of numerical calculations. (C) 2001 MAIK ``Nauka/Interperiodica\{''\}.},
