Multiple soliton-like solutions for \((2+1)\)-dimensional dispersive long-wave equations. (English) Zbl 0940.35180

Summary: By using a homogeneous balance method, multiple-soliton-like solutions of the \((2+1)\)-dimensional dispersive long-wave equation \[ \begin{aligned} u_{ty}+ \eta_{xx}+ u_x u_y+ uu_{xy} & = 0,\\ \eta_t+ (u\eta+ u+ y_{xy})_x & = 0\end{aligned} \] are constructed. The method used here can be generalized to a wide class of nonlinear evolution equations.
