報告摘要:
In this talk, we will study the existence, uniqueness, and moment properties of mild solutions for a class of space-time fractional stochastic heat equation driven by Gaussian noise that is rough in space. The governing operators consist of a Caputo time-fractional derivative of order $\beta\in(0,1)$ and a space-fractional Laplacian of order $\alpha\in(1,2)$. We obtain sharp upper and lower moment bounds, establish weakly full intermittency, and derive the explicit noise excitation index $\frac{2\alpha}{\alpha+2\beta(H-1)}$.
