| 摘要: | 研究了一般M?bius几何中的曲线流, 证明了一类多分量的Camassa-Holm方程等价于M?bius几何中的一个不变曲线流, 此方程是两分量Camassa-Holm方程的多分量推广, 也可以看成是一类多分量KdV系统的对偶可积系统. 最后得到了此方程的一个退化情形的尖峰孤子解. |
| Abstract: | In this paper, we study curve flows in general M?bius geometry, and prove that a class of multi-component Camassa-Holm equations are equivalent to an invariant curve flow in M?bius geometry, which is a multi-component generalization of the two-component Camassa-Holm equation, and can also be regarded as a dual integrable system of a class of multi-component KdV systems. We also obtain a peaked solution for a degradation case of multi-component Camassa-Holm equations. |
