Burgers-Hilbert方程的不稳定激波形成

Unstable shock formation of the Burgers-Hilbert equation

Ruoxuan Yang

摘要:

本文证明了arXiv:2006.05568中Burgers-Hilbert方程不稳定激波的存在性.更准确地说,我们构造光滑的初始数据与有限的$H^9$ -范数,使自相似坐标系中的解决方案是渐近的第一个不稳定的解决方案的自相似无粘Burgers方程。爆破剖面是一个具有Hölder 1/5连续性的尖点,具有明确的爆破时间和位置。与先前建立的稳定冲击不同,初始数据不能取在开集中;相反,我们通过牛顿迭代来控制两个不稳定方向。

英文摘要:

This paper proves the existence of unstable shocks of the Burgers-Hilbert equation conjectured in arXiv:2006.05568. More precisely, we construct smooth initial data with finite $H^9$-norm such that the solution in self-similar coordinates is asymptotic to the first unstable solution to the self-similar inviscid Burgers equation. The blowup profile is a cusp with Hölder 1/5 continuity with explicit blowup time and location. Unlike the previously established stable shocks, the initial data cannot be taken in an open set; instead, we control the two unstable directions by Newton's iteration.
