Camassa-Holm方程在加权空间中的分解和持久性

Breakdown for the Camassa-Holm Equation Using Decay Criteria and Persistence in Weighted Spaces

Lorenzo Brandolese

摘要:

我们给出了Camassa-Holm方程强解在无穷远处衰减的一个充分条件:当初始数据在无穷远处衰减快于孤子时,波将破裂.在数据衰减慢于孤子的情况下,我们提供的持久性结果的解决方案在加权$L^p$ -空间,一个大类的中等权重。明确的渐近配置文件说明这些结果的最优性。

英文摘要:

We exhibit a sufficient condition in terms of decay at infinity of the initial data for the finite time blowup of strong solutions to the Camassa--Holm equation: a wave breaking will occur as soon as the initial data decay faster at infinity than the solitons. In the case of data decaying slower than solitons we provide persistence results for the solution in weighted $L^p$-spaces, for a large class of moderate weights. Explicit asymptotic profiles illustrate the optimality of these results.
