elliptic equations with random coefficients, which is closely related to the long-time …

The additive structure of elliptic homogenization

S Armstrong, T Kuusi, JC Mourrat - Inventiones mathematicae, 2017 - Springer
One of the principal difficulties in stochastic homogenization is transferring quantitative
ergodic information from the coefficients to the solutions, since the latter are nonlocal …

We investigate volume-element sampling strategies for the stochastic homogenization of
particle-reinforced composites and show, via computational experiments, that an improper …

A regularity theory for random elliptic operators

A Gloria, S Neukamm, F Otto - Milan journal of mathematics, 2020 - Springer
Since the seminal results by Avellaneda & Lin it is known that elliptic operators with periodic
coefficients enjoy the same regularity theory as the Laplacian on large scales. In a recent …

The structure of fluctuations in stochastic homogenization

M Duerinckx, A Gloria, F Otto - Communications in Mathematical Physics, 2020 - Springer
Four quantities are fundamental in homogenization of elliptic systems in divergence form

The corrector in stochastic homogenization: optimal rates, stochastic integrability, and fluctuations

A Gloria, F Otto - arXiv preprint arXiv:1510.08290, 2015 - arxiv.org
We consider uniformly elliptic coefficient fields that are randomly distributed according to a
stationary ensemble of a finite range of dependence. We show that the gradient and flux …

Higher-order pathwise theory of fluctuations in stochastic homogenization

Bias in the representative volume element method: periodize the ensemble instead of its realizations

N Clozeau, M Josien, F Otto, Q Xu - Foundations of Computational …, 2024 - Springer
We study the representative volume element (RVE) method, which is a method to
approximately infer the effective behavior a hom of a stationary random medium. The latter is …

The choice of representative volumes in the approximation of effective properties of random materials

J Fischer - Archive for Rational Mechanics and Analysis, 2019 - Springer
The effective large-scale properties of materials with random heterogeneities on a small
scale are typically determined by the method of representative volumes: a sample of the …
