$μ$ -Camassa-Holm方程的解析Cauchy问题及其非拟线性形式

Analytic Cauchy problem for the $μ$-Camassa-Holm equation and its non-quasilinear version

Hideshi Yamane

摘要:

在复解析框架下,我们求解了Khesin-Lenells-Misio-Chek的$μ$ -Camassa-Holm积分偏微分方程及其非拟线性形式的Cauchy问题.这些方程在两个层次上具有非局部性质:它们涉及负阶的伪微分算子,并且该算子定义为未知函数的积分。我们证明了唯一的可解性的柯西问题,并提供了一个估计的寿命的解决方案。我们的方法是Ovsyannikov型参数由Batrostichi-Himonas-Petronilho关于一个规模的Banach空间的解析函数,但非拟线性处理的方式与他们不同。事实上,我们使用的是一个简单的约化,这只是一个经典技巧的非局部版本。

英文摘要:

We solve the Cauchy problems for the $μ$-Camassa-Holm integro-partial differential equation of Khesin-Lenells-Misiołek and its non-quasilinear version introduced by Qu-Fu-Liu in the complex-analytic framework. These equations have nonlocal nature at two levels: they involve a pseudo-differential operator of negative order and this operator is defined in terms of an integral of the unknown function. We prove unique solvability of the Cauchy problems and provide an estimate of the lifespan of the solutions. Our method is the Ovsyannikov type argument by Batrostichi-Himonas-Petronilho about a scale of Banach spaces of analytic functions, but the non-quasilinearity is dealt with in a different way from theirs. Indeed, we use a simple reduction which is just a nonlocal version of a classical trick.
