无发散漂移随机均匀化中的大尺度正则性

Large-scale regularity in stochastic homogenization with divergence-free drift

Benjamin Fehrman

摘要:

我们提供了一个简单的证明淬火随机均匀化的随机环境的平均为零,发散自由漂移的假设下,漂移承认一个固定的$L^d$ -可积流矩阵在$d\geq 3$或$L^{2+δ}$ -可积流矩阵在$d=2$。此外,我们证明了环境几乎必然满足一个大规模的Hölder正则性估计和一阶Liouville原理。

英文摘要:

We provide a simple proof of quenched stochastic homogenization for random environments with a mean zero, divergence-free drift under the assumption that the drift admits a stationary $L^d$-integrable stream matrix in $d\geq 3$ or an $L^{2+δ}$-integrable stream matrix in $d=2$. In addition, we prove that the environment almost surely satisfies a large-scale Hölder regularity estimate and first-order Liouville principle.
