周期Camassa-Holm方程的Lipschitz度量

Lipschitz metric for the periodic Camassa-Holm equation

Katrin Grunert, Helge Holden, Xavier Raynaud

摘要:

研究了周期Camassa-Holm方程$u_t-u_{xxt}+κu_x+3uu_x-2u_xu_{xx}-uu_{xxx}=0$在初值为$u_0$时Cauchy问题保守解的稳定性.特别是,我们推导出一个新的Lipschitz度量$d_\D$的性质,两个解决方案$u$和$v$的方程,我们有$d_\D(u(t),v(t))\le e^{Ct} d_\D(u_0,v_0)$。阐明了该度量与$H^1_{\rm per}$和$L^\infty_{\rm per}$中常用范数之间的关系。

英文摘要:

We study stability of conservative solutions of the Cauchy problem for the periodic Camassa-Holm equation $u_t-u_{xxt}+κu_x+3uu_x-2u_xu_{xx}-uu_{xxx}=0$ with initial data $u_0$. In particular, we derive a new Lipschitz metric $d_\D$ with the property that for two solutions $u$ and $v$ of the equation we have $d_\D(u(t),v(t))\le e^{Ct} d_\D(u_0,v_0)$. The relationship between this metric and usual norms in $H^1_{\rm per}$ and $L^\infty_{\rm per}$ is clarified.
