水波的飞溅奇点

Splash singularity for water waves

Angel Castro, Diego Córdoba, Charles Fefferman, Francisco Gancedo, Javier Gómez-Serrano

摘要:

我们表现出光滑的初始数据的2D水波方程,我们证明了光滑的接口在有限时间内崩溃。此外,我们显示的稳定性结果与数值证据,存在的解决方案的二维水波方程,从一个图形开始,翻转和崩溃的飞溅奇点(自相交曲线在一个点)在有限的时间。

英文摘要:

We exhibit smooth initial data for the 2D water wave equation for which we prove that smoothness of the interface breaks down in finite time. Moreover, we show a stability result together with numerical evidence that there exist solutions of the 2D water wave equation that start from a graph, turn over and collapse in a splash singularity (self intersecting curve in one point) in finite time.
