Camassa-Holm方程代数几何解的新构造及其数值计算

New construction of algebro-geometric solutions to the Camassa-Holm equation and their numerical evaluation

C. Kalla, C. Klein

摘要:

一个独立的推导的解决方案的Camassa-Holm方程的多维θ函数,提出了使用的方法基于费伊的身份。从底层实超椭圆曲面拓扑的角度研究了这些解的真实性和光滑性条件。数值研究的解决方案的具体例子,也在极限的表面退化到黎曼球,孤子和尖点出现。

英文摘要:

An independent derivation of solutions to the Camassa-Holm equation in terms of multi-dimensional theta functions is presented using an approach based on Fay's identities. Reality and smoothness conditions are studied for these solutions from the point of view of the topology of the underlying real hyperelliptic surface. The solutions are studied numerically for concrete examples, also in the limit where the surface degenerates to the Riemann sphere, and where solitons and cuspons appear.
