具有表面张力的二维水波的整体正则性

Global regularity for 2d water waves with surface tension

Alexandru D. Ionescu, Fabio Pusateri

摘要:

我们认为,充分无旋水波系统的表面张力和没有重力在二维(毛细波系统),并证明了全球的正则性和修改散射适当小和局部扰动的平坦界面。我们的分析的一个重要的一点是开发一个足够强大的方法,能量估计和色散分析的基础上,这使我们能够处理强奇异性所产生的正常形式的方法和非线性散射的应用程序中的时间共振。因此,我们能够考虑一个合适的一类具有有限能量的扰动,但没有其他的动量条件。我们的分析的一部分依赖于一个新的治疗的狄利克雷-诺依曼算子在二维这是独立的利益。因此,本文的结果是完备的。

英文摘要:

We consider the full irrotational water waves system with surface tension and no gravity in dimension two (the capillary waves system), and prove global regularity and modified scattering for suitably small and localized perturbations of a flat interface. An important point of our analysis is to develop a sufficiently robust method, based on energy estimates and dispersive analysis, which allows us to deal with strong singularities arising from time resonances in the applications of the normal form method and nonlinear scattering. As a result, we are able to consider a suitable class of perturbations with finite energy, but no other momentum conditions. Part of our analysis relies on a new treatment of the Dirichlet-Neumann operator in dimension two which is of independent interest. As a consequence, the results in this paper are self-contained.
