一类广义Camassa-Holm方程的自伴性

Self-adjointness of a generalized Camassa-Holm equation

N. H. Ibragimov, R. Khamitova, A. Valenti

摘要:

众所周知,Camassa-Holm方程具有许多KdV型方程的显著性质。本文证明了它与KdV方程又有一个共同的性质。也就是说,Algimov证明了KdV和修正的KdV方程是自伴的。从Camassa-Holm方程的推广出发,证明了Camassa-Holm方程是自伴的.这个性质很重要,例如,对于构造与所讨论的方程的对称性相关的守恒律。相应地,我们利用广义Camassa-Holm方程的对称性构造了它的守恒律。

英文摘要:

It is well known that the Camassa-Holm equation possesses numerous remarkable properties characteristic for KdV type equations. In this paper we show that it shares one more property with the KdV equation. Namely, Ibragimov has shown that the KdV and the modified KdV equations are self-adjoint. Starting from the generalization of the Camassa-Holm equation, we prove that the Camassa-Holm equation is self-adjoint. This property is important, e.g. for constructing conservation laws associated with symmetries of the equation in question. Accordingly, we construct conservation laws for the generalized Camassa-Holm equation using its symmetries.
