sinh-Gordon方程椭圆解的稳定性

Stability of elliptic solutions to the sinh-Gordon equation

Wen-Rong Sun, Bernard Deconinck

摘要:

利用sinh-Gordon方程的可积性,我们证明了其椭圆解的谱稳定性。通过构造一个李雅普诺夫功能使用高阶守恒量的sinh-Gordon方程,我们表明,这些椭圆形的解决方案是轨道稳定的次谐波扰动的任意周期。

英文摘要:

Using the integrability of the sinh-Gordon equation, we demonstrate the spectral stability of its elliptic solutions. By constructing a Lyapunov functional using higher-order conserved quantities of the sinh-Gordon equation, we show that these elliptic solutions are orbitally stable with respect to subharmonic perturbations of arbitrary period.
