However, we observe that for all cases in which k ⩾ 1 and l ⩾ 1, convergence was obtained and observed to be at approximately optimal rates in the sense that the L 2 —rate of velocity … Webb8 nov. 2024 · In this article, we consider the stochastic Cahn--Hilliard equation driven by additive noise. We discretize the equation by exploiting the spectral Galerkin method in space and a temporal accelerated implicit Euler method. Based on optimal regularity estimates of both exact and numerical solutions, we prove that the proposed numerical …
