| contents | This article mainly proves the existence of stationary correctors under space-time spectral gap conditions, which exhibit different properties from those of elliptic operator correctors. Additionally, new flux correctors and their fluctuation estimates are introduced.Based on this, we obtain the optimal homogenization error in the sense of strong and weak norms on C1 cylinders by using the duality and distance-weighted arguments, in which the (weighted) annealed Calderon-Zygmund estimates coupled with a novel form of the minimal radius are developed. Throughout the paper, no small-scale smoothness of the coefficients is used. |
