广义Zakharov-Kuznetsov方程的极大函数估计和局部适定性

Maximal function estimates and local well-posedness for the generalized Zakharov--Kuznetsov equation

Felipe Linares, João P. G. Ramos

摘要:

证明了自由Zakharov-Kuznetsov方程的酉群的一个高维形式的Schahartz估计.作为一个产品,我们推导出最大的估计,使我们能够证明本地适定性的广义Zakharov-Kuznetsov方程在整个亚临界的情况下,每当$d \ge 4, k \ge 4,$补充最近的结果Kinoshita和Herr-Kinoshita。最后,我们使用一些最大的估计,以证明逐点收敛结果的流动的广义Zakharov-Kuznetsov方程在任何方面,在同一精神的最近的手稿Compaan,Lucà和Staffilani。

英文摘要:

We prove a high-dimensional version of the Strichartz estimates for the unitary group associated to the free Zakharov--Kuznetsov equation. As a by--product, we deduce maximal estimates which allow us to prove local well-posedness for the generalized Zakharov--Kuznetsov equation in the whole subcritical case whenever $d \ge 4, k \ge 4,$ complementing the recent results of Kinoshita and Herr--Kinoshita. Finally, we use some of those maximal estimates in order to prove pointwise convergence results for the flow of the generalized Zakharov--Kuznetsov equation in any dimension, in the same spirit of a recent manuscript by Compaan, Lucà and Staffilani.
