Abstract:This talk introduces a high-order
discontinuous Galerkin (DG)
method for the Camassa-Holm-Kadomtsev-Petviashvili(CH-KP)
type equations on Cartesian meshes. The significant part of the simulation for
the CH-KP type equations lies in the treatment for the integration operator ∂^(-1). Our
proposed DG method deals with itelement by element, which is efficient and applicable to most solutions. Using
the instinctive energy of the original PDE as
a guiding principle, the DG scheme can be proved as an energy stable numerical
scheme. In addition, the semi-discrete error estimates results for the
nonlinear case are derived without any priori assumption. Several numerical
experiments demonstrate the capability of our schemesfor
various types of solutions.
