Query: Long time behaviour for a class of low-regularity solutions of the
  Camassa-Holm equation   In this paper, we investigate the long time behaviour for a class of
low-regularity solutions of the Camassa-Holm equation given by the
superposition of infinitely many interacting traveling waves with corners at
their peaks.
