Abstract: AbstractThe dressing method based on 3×3 matrix∂-problem is extended to study the long-short waves equation with the cases σ = ±1. The soliton solutions for the long-short wave equation for σ = ±1 are given by means of the properties of Cauchy matrix. It is shown that the long-short wave equation for σ = 1 has the cusp solitons.
