AI总结:

本文提出基于新改写形式的保结构离散化方法,用于求解本内特-奥诺方程等非局部偏微分方程,通过数值实验验证了方法的有效性。

摘要:

本文考虑了本内特和本内特-奥诺方程的数值积分。这些方程是非局部偏微分方程,涉及希尔伯特变换,因此至今很少有保结构积分器被提出。本文提出了一种新的方程改写形式,并基于此提出了新的保结构离散化方法。数值实验证实了所提积分器的有效性。

英文摘要:

The numerical integration of the Benjamin and Benjamin--Ono equations are considered. They are non-local partial differential equations involving the Hilbert transform, and due to this, so far quite few structure-preserving integrators have been proposed. In this paper, a new reformulation of the equations is stated, and new structure-preserving discretizations are proposed based on it. Numerical experiments confirm the effectiveness of the proposed integrators.
