| Abstract: |
| In this paper, we consider the homogenization problem of semilinear parabolic stochastic partial differential equations ( SPDEs ) with homogeneous Neumann boundary conditions defined on $\textbf{R}_{+} × [ 0, 1 ]^d$ with high-frequency oscillatory random potential, where $d =1,2$ or $ 3 $, by using regularity structures, the main conclusion is that the solution of the system of equations will converge to the solution of a deterministic parabolic PDEs in probability. |
