摘要:

使用粘性近似方法研究了一类高阶Camasa-Holm型方程. 推出了该类方程粘性解的高阶可积性估计及其空间导数的上界估计, 从而证明了该类方程整体弱解的存在性.

关键词: 整体弱解, 粘性近似, Camassa-Holm-type方程

Abstract:

The viscous approximation technique is employed to investigate the existence of global weak solutions for a high-order Camassa-Holm type equation. A higher integrability estimate of the viscous solutions for the equation and the upper bound estimate on the space derivative of its viscous solutions are derived to prove the existence.

Key words: Global weak solutions, Viscous approximations, Camassa-Holm-type equation
