stochastic Cahn–Hilliard–Cook equation. The Ciarlet–Raviart mixed finite element method is
applied to solve the fourth-order equation. In order to estimate the mild solution, we use finite
elements for space discretization and the semi-implicit Euler–Maruyama method in time. For
the stochastic scheme, we use the multilevel method to decrease the computational cost
(compared to the Monte Carlo method). We implement the method to solve three specific …
