Abstract The fifth-order KdV-type equation models many physical phenomena such as gravity-capillary waves and magneto-sound propagation in plasma. Dual-Petrov-Galerkin approximations to the fifth-order KdV equation is considered. The key idea of this method developed by Jie Shen is to use the trial functions satisfying the underlying boundary conditions of the differential equation and the test functions satisfying the dual boundary conditions. Our theoretical analysis and numerical results indicate the proposed dual-Petrov-Galerkin method is extremely accurate and efficient. This is a joint work with Jie Shen and Jiahong Wu.
