具有非线性阻尼和源项的随机Wave Equations

Stochastic Wave Equations with Nonlinear Damping and Source Terms

Hongjun Gao, Boling Guo, Fei Liang

摘要:

本文讨论了一类含有非线性阻尼项$|u_t|^{q-2}u_t$和$|u|^{p-2}u$型源项的随机波动方程的初边值问题.首先利用Galerkin逼近方法证明了解的局部存在唯一性,并证明了解是整体的。其次,通过适当的能量不等式,使$p>q$随机方程的局部解在能量意义下以正概率爆破或爆炸性爆破。

英文摘要:

In this paper, we discuss an initial boundary value problem for the stochastic wave equation involving the nonlinear damping term $|u_t|^{q-2}u_t$ and a source term of the type $|u|^{p-2}u$. We firstly establish the local existence and uniqueness of solution by the Galerkin approximation method and show that the solution is global for $q\geq p$. Secondly, by an appropriate energy inequality, the local solution of the stochastic equations will blow up with positive probability or explosive in energy sense for $p>q$.
