Homogenization and Corrector Theory for Linear Transport in Random Media

چکیده
We consider the theory of correctors to homogenization in stationary transport equations with rapidly oscillating, random coefficients. Let ε 1 be the ratio of the correlation length in the random medium to the overall distance of propagation. As ε ↓ 0, we show that the heterogeneous transport solution is well-approximated by a homogeneous transport solution. We then show that the rescaled corrector converges in (probability) distribution and weakly in the space and velocity variables, to a Gaussian process as an application of a central limit result. The latter result requires strong assumptions on the statistical structure of randomness and is proved only for random processes constructed by means of a Poisson point process.

A Corrector Theory for Diffusion-Homogenization Limits of Linear Transport Equations
This paper concerns the diffusion-homogenization of transport equations when both the adimensionalized scale of the heterogeneities α and the adimensionalized mean-free path ε converge to 0. When α = ε, it is well known that the heterogeneous transport solution converges to a homogenized diffusion solution. We are interested here in the situation where 0 < ε α 1 and in the respective rates of c...
متن کاملCorrector Theory for MsFEM and HMM in Random Media
Abstract. We analyze the random fluctuations of several multi-scale algorithms such as the multi-scale finite element method (MsFEM) and the finite element heterogeneous multi-scale method (HMM), that have been developed to solve partial differential equations with highly heterogeneous coefficients. Such multi-scale algorithms are often shown to correctly capture the homogenization limit when t...
متن کاملRandom homogenization and convergence to integrals with respect to the Rosenblatt process
This paper concerns the random fluctuation theory of a one dimensional elliptic equation with highly oscillatory random coefficient. Theoretical studies show that the rescaled random corrector converges in distribution to a stochastic integral with respect to Brownian motion when the random coefficient has short-range correlation. When the random coefficient has long range correlation, it was s...
متن کاملLiouville Principles and a Large-Scale Regularity Theory for Random Elliptic Operators on the Half-Space
We consider the large-scale regularity of solutions to second-order linear elliptic equations with random coefficient fields. In contrast to previous works on regularity theory for random elliptic operators, our interest is in the regularity at the boundary: We consider problems posed on the halfspace with homogeneous Dirichlet boundary conditions and derive an associated C1,α-type large-scale ...
متن کاملA PRELUDE TO THE THEORY OF RANDOM WALKS IN RANDOM ENVIRONMENTS
A random walk on a lattice is one of the most fundamental models in probability theory. When the random walk is inhomogenous and its inhomogeniety comes from an ergodic stationary process, the walk is called a random walk in a random environment (RWRE). The basic questions such as the law of large numbers (LLN), the central limit theorem (CLT), and the large deviation principle (LDP) are ...
