Dark solitons of the Qiao's hierarchy
arXiv:1211.4249 · doi:10.1063/1.4764859
Abstract
We obtain a class of soliton solutions of the integrable hierarchy which has been put forward in a series of works by Z. Qiao. The soliton solutions are in the class of real functions approaching constant value fast enough at infinity, the so-called 'dark solitons'.
