摘要:

In this talk, a class of implicit and explicit high-order finite difference schemes developed in SCCS for solving some distinguished integrable equations will be presented. For retaining the Hamiltonian nature of the equations under investigation, symplectic temporal schemes rendering a second-order accurate explicit scheme and a sixth-order accurate implicit scheme have been developed. For retaining dispersive nature of the equations under investigation, we minimize the error between the numerical and exact dispersion relation equations. In this presentation, one/two-component Camassa-Holm equations, Degasperis-Procesi equation, one/two-component Hunter-Saxton equations and cubic nonlinear Schrödinger equation are considere
