摘要
Using the variational-asymptotic method we develop the theory of amplitude modulation of waves governed by Korteweg-de Vries (KdV) equation. Two asymptotic solutions describing the amplitude modulation of trains of solitons and of positons are obtained. The comparison with the exact solutions of KdV equation shows quite excellent agreement. (C) 2014 Elsevier Ltd. All rights reserved.
