Camassa-Holm方程推广的适定性、行波和几何性质

Well-posedness, travelling waves and geometrical aspects of generalizations of the Camassa-Holm equation

Priscila Leal da Silva, Igor Leite Freire

摘要:

在本文中,我们考虑一个四参数方程,其中包括Camassa-Holm和Dulling-Gottwald-Holm方程。利用Kato方法证明了一个包含该方程的Cauchy问题解的存在唯一性。还研究了方程的二阶守恒律。从这些守恒律出发,我们建立了所研究方程解的一些性质,并求出了它的一个求积,所得的求积在所研究方程的有界行波解的分类中是十分重要的。我们还找到了一些明确的解决方案,在椭圆积分。最后,我们分类的成员描述伪球面方程。

英文摘要:

In this paper we consider a four-parameter equation including the Camassa-Holm and the Dulling-Gottwald-Holm equations, among others. We prove the existence and uniqueness of solutions to a Cauchy problem involving the equation using Kato's approach. Conservation laws of the equation up to second order are also investigated. From these conservation laws we establish some properties of the solutions of the equation under consideration and we also find a quadrature for it. The quadrature obtained is of capital importance in a classification of bounded travelling wave solutions of the equation studied. We also find some explicit solutions, given in terms of elliptic integrals. Finally, we classify the members of the equation describing pseudo-spherical surfaces.
