Abstract:
In this letter, we construct a kind of new Darboux transformation forthe (1+1)-dimensional higher-order Broer-Kaup (HBK) system withthe help of a gauge transformation of a spectral problem. By applyingthis new Darboux transformation, some new soliton-like solutions ofthe (1+1)-dimensional HBK system are obtained.
