三维广义 Zakharov-Kuznetsov 方程解的色散爆破

Dispersive blow-up for solutions to three dimensional generalized Zakharov-Kuznetsov equations

Yingzhe Ban, Minjie Shan

AI总结:

本文研究三维广义 Zakharov-Kuznetsov 方程解的色散爆破现象,通过构造光滑初始数据使全局解在有理数时间点失去 $C^{1}$ 正则性,其核心方法是构造线性解并证明非线性平滑估计。

摘要:

我们阐述三维广义 Zakharov-Kuznetsov 方程解的色散爆破现象。特别地,我们构造光滑初始数据,使得相应的全局解在包含所有有理数的零测集中的时间 $t$ 处不是 $C^{1}$ 的,但在所有作为一般无理数的时间 $t$ 处是 $C^{1}$ 的。关键在于构造展现此现象的线性解,并证明完整非线性模型的非线性平滑估计。

英文摘要:

We illustrate the dispersive blow up phenomena of the solutions of three dimensional generalized Zakharov-Kuznetsov equations. In particular, we construct smooth initial data such that, the associated global solutions fail to be $C^{1}$ at time $t$ in a null set containing all rational numbers, but are $C^{1}$ at all times $t$ which are generic irrational numbers. The key ingredient are to construct linear solutions which exhibit such phenomena and to prove nonlinear smoothing estimates for the full nonlinear model.
