退化随机环境的定量均匀化

Quantitative homogenization of degenerate random environments

Arianna Giunti, Jean-Christophe Mourrat

摘要:

我们研究具有随机系数的离散线性发散形式算子,也称为随机电导模型。我们假设电导是有界的,独立的和固定的,电导的法律可能取决于相关的边缘的方向。我们给出了一个简单的充要条件松弛的环境看到的粒子是扩散的,在每个多项式矩的意义。作为结果,我们得到多项式矩估计的校正。

英文摘要:

We study discrete linear divergence-form operators with random coefficients, also known as the random conductance model. We assume that the conductances are bounded, independent and stationary; the law of a conductance may depend on the orientation of the associated edge. We give a simple necessary and sufficient condition for the relaxation of the environment seen by the particle to be diffusive, in the sense of every polynomial moment. As a consequence, we derive polynomial moment estimates on the corrector.
