时空分数阶随机偏微分方程的路径爆破

Pathwise Blowup of space-time fractional SPDEs

Chang-Song Deng, Wei Liu, Erkan Nane

摘要:

讨论了一类时空分数阶随机偏微分方程在几乎几乎必然意义下的有限时间爆破。考虑了白噪声和色噪声两种情况。当空间域有界时,得到了爆破与Osgood条件之间的充分和必要条件.当空间域为全空间时,得到了爆破的充分条件。本文的结果可以看作是Foondun和Nualart,2021中某些结果的推广。

英文摘要:

The finite time blowup in the almost sure sense of a class of space-time fractional stochastic partial differential equations is discussed. Both the cases of white noise and colored noise are considered. The sufficient and necessary condition between the blowup and Osgood condition is obtained when the spatial domain is bounded. And the sufficient condition for the blowup is obtained when the spatial domain is the whole space. The results in this paper could be regarded as extensions to some results in Foondun and Nualart, 2021.
