Sine-Gordon方程的一个新的可积推广

On a novel integrable generalization of the sine-Gordon equation

J. Lenells, A. S. Fokas

摘要:

我们考虑一个可积的推广的正弦戈登(SG)方程,较早来自作者之一,使用双哈密顿方法。该方程与sG方程的关系与Camassa-Holm方程与KdV方程的关系相同。(a)导出一个拉克斯对。(b)使用拉克斯对来解决线上的初值问题。(c)分析孤子。(d)证明了广义sG和sG方程通过一个Liouville变换联系起来。(e)导出守恒定律。(f)分析行波解。

英文摘要:

We consider an integrable generalization of the sine-Gordon (sG) equation that was earlier derived by one of the authors using bi-Hamiltonian methods. This equation is related to the sG equation in the same way that the Camassa-Holm equation is related to the KdV equation. In this paper we: (a) Derive a Lax pair. (b) Use the Lax pair to solve the initial value problem on the line. (c) Analyze solitons. (d) Show that the generalized sG and sG equations are related by a Liouville transformation. (e) Derive conservation laws. (f) Analyze traveling-wave solutions.
