Alisson Darós, Lynnyngs Kelly Arruda Saraiva de Paiva

摘要:

我们发现,波破碎发生的修改Camassa-Holm(mCH)方程。接下来,我们分类所有的行波解的修改Camassa-Holm方程在弱意义下,通过参数化的最大值,最小值和波速常数。这个方程示出承认除了更流行的解决方案,如平滑行波和peakons,一些不那么知名的行波,例如,扭结,cuspons,复合波和stumpons。此外,还发现了用雅可比椭圆函数表示的显式峰。

英文摘要:

We show that wave breaking occurs for the modified Camassa-Holm (mCH) equation. Next we classify all traveling wave solutions of the modified Camassa-Holm equation in the weak sense via parametrization of their maxima, minima and wave velocity constants. This equation is shown to admit in addition to more popular solutions like smooth traveling waves and peakons, some not so well-known traveling waves as, for example, kinks, cuspons, composite waves and stumpons. Moreover, explicit peakons in terms of Jacobian elliptic functions are found.
