Abstract:
We consider the following parabolic SPDEs: \[ \frac{\partial}{\partial t} u(t,x;\lambda) =\triangle u(t,x;\lambda) +b(u(t,x;\lambda)) +\lambda\sigma\left(u(t,x;\lambda)\right)\frac{\partial^2}{\partial t\partial x}\xi(t,x), \] subject to nonrandom initial data $u_0(x)$ where $\xi(t,x)$ is a Gaussian noise. One motivation for studying this model is a physical phenomena: intermittency, so we will introduce it first. In this talk, we will discuss limiting behaviors of the solutions $u(t,x;\lambda)$ in variant $b(x)$ and how $\lambda$ effects their limiting behaviors.
