临界拟线性Smoluchowski-Poisson方程组径向对称解的有限时间爆破

Finite time blow-up for radially symmetric solutions to a critical quasilinear Smoluchowski-Poisson system

Tomasz Cieślak, Philippe Laurençot

摘要:

有限时间爆破所示发生的径向对称解的临界准线性Smoluchowski-Poisson系统提供的初始条件的质量超过一个明确的阈值。在超临界的情况下,爆破显示发生任何积极的质量。这个证明依赖于一个新的维里类型的恒等式。

英文摘要:

Finite time blow-up is shown to occur for radially symmetric solutions to a critical quasilinear Smoluchowski-Poisson system provided that the mass of the initial condition exceeds an explicit threshold. In the supercritical case, blow-up is shown to take place for any positive mass. The proof relies on a novel identity of virial type.
