摘要
We first note that the improved Boussinesq equation has a multisymplectic structure.Based on it,a multisymplectic scheme is proposed.Dispersion relations analysis and linear stability analysis show that the proposed scheme has excellent properties.Numerical results confirm the excellent long-term behavior of the proposed scheme.
