摘要:In this talk, we consider a bidirectional fifth-order partial differential equation. By means of the prolongation structure method of Wahlquist and Estabrook, we construct a Lax representation for this equation. This enables us to confirm its integrability and identify it as the potential second order flow in a Gelfand-Dickey hierarchy. We also use Darboux transformation and present the multi-soliton solutions in Wronskian form. Finally, we comment on a more general bidirectional partial differential equation.
