径向能量临界wave equation的II型爆破速度的界

Bounds on the speed of type II blow-up for the energy critical wave equation in the radial case

Jacek Jendrej

摘要:

我们考虑了径向数据在空间维$N\in \{3, 4, 5\}$中的聚焦能量临界波动方程。我们研究II型爆破解决方案,集中一个泡沫的能量。已知这样的解在能量空间中分解为气泡和渐近分布的总和。我们证明的情况下,当渐近轮廓是充分经常的爆破速度的界限。这些界限在维度$N = 5$中是最优的。我们还证明了,如果渐近轮廓是充分经常的,那么它不能严格负的原点。

英文摘要:

We consider the focusing energy-critical wave equation in space dimension $N\in \{3, 4, 5\}$ for radial data. We study type II blow-up solutions which concentrate one bubble of energy. It is known that such solutions decompose in the energy space as a sum of the bubble and an asymptotic profile. We prove bounds on the blow-up speed in the case when the asymptotic profile is sufficiently regular. These bounds are optimal in dimension $N = 5$. We also prove that if the asymptotic profile is sufficiently regular, then it cannot be strictly negative at the origin.
