Abstract

Concerned with elliptic operators with stationary random coefficients governed by linear or nonlinear mixing conditions and bounded (or unbounded) C1 domains, this paper mainly studies (weighted) annealed Calderón-Zygmund estimates, some of which are new even in a periodic setting. Stronger than some classical results derived by a perturbation argument in the deterministic case, our results own a scaling-invariant property, which additionally requires the non-perturbation method (based upon a quantitative homogenization theory and a set of functional analysis techniques) recently developed by M. Joisen and F. Otto \citeJosien-Otto22. To handle boundary estimates in certain UMD (unconditional martingale differences) spaces, we hand them over to Shen's real arguments \citeShen05, Shen23 instead of using Mikhlin's theorem. As a by-product, we also established ``resolvent estimates''. The potentially attractive part is to show how the two powerful kernel-free methods work together to make the results clean and robust.
