摘要
In this paper, we obtain the soliton solutions for the "good" Boussinesq equation on a constant background.Based on the asymptotic analysis of the solutions, we find that this equation admits both the elastic and resonant soliton interactions, as well as various partially inelastic interactions comprised of such two fundamental interactions. Via picture drawing, we present some examples of soliton interactions on nonzero backgrounds. Our results enrich the knowledge of soliton interactions in the(1+1)-dimensional integrable equation with a single field.
