Stability of the train of $N$ solitary waves for the two-component Camassa-Holm shallow water system

27 Sep 2015  ·  Liu Xingxing ·

Considered herein is the integrable two-component Camassa-Holm shallow water system derived in the context of shallow water theory, which admits blow-up solutions and the solitary waves interacting like solitons. Using modulation theory, and combining the almost monotonicity of a local version of energy with the argument on the stability of a single solitary wave, we prove that the train of $N$ solitary waves, which are sufficiently decoupled, is orbitally stable in the energy space $H^1(\R)\times L^2(\R)$...
