能量超临界波的适定性和不适定性问题

Well and ill-posedness issues for energy supercritical waves

Slim Ibrahim, Mohamed Majdoub, Nader Masmoudi

摘要:

研究一类能量超临界半线性波动方程的初值问题。我们建立了局部存在性在适当的空间连续流。我们也得到了一些不适定性/弱不适定性结果。证明使用有限的传播速度和相关的常微分方程的定量研究。它不需要方程的任何标度不变性。

英文摘要:

We investigate the initial value problem for some energy supercritical semilinear wave equations. We establish local existence in suitable spaces with continuous flow. We also obtain some ill-posedness/weak ill-posedness results. The proof uses the finite speed of propagation and a quantitative study of the associated ODE. It does not require any scaling invariance of the equation.
