强扰动wave equations的爆破行为

Blowup behavior of strongly perturbed wave equations

Roland Donninger, David Wallauch

摘要:

研究了一类具有聚焦超临界幂非线性项的强扰动波动方程在三维空间中的爆破行为。我们证明了未扰动方程的常微分方程爆破轮廓仍然描述了稳定爆破的渐近性。因此,稳定的ODE型爆破被认为是一个普遍的现象,存在于一个大类的半线性波动方程。

英文摘要:

We study the blowup behavior of a class of strongly perturbed wave equations with a focusing supercritical power nonlinearity in three spatial dimensions. We show that the ODE blowup profile of the unperturbed equation still describes the asymptotics of stable blowup. As a consequence, stable ODE-type blowup is seen to be a universal phenomenon that exists in a large class of semilinear wave equations.
