完全非线性一致椭圆型方程的随机均匀化

Stochastic homogenization of fully nonlinear uniformly elliptic equations revisited

Scott N. Armstrong, Charles K. Smart

摘要:

本文给出了非发散形式椭圆型方程随机均匀化的障碍问题方法的一个简化表示。我们的论证也适用于依赖于未知函数的梯度的方程。在后一种情况下,我们克服了困难所造成的缺乏估计的一阶导数的近似校正通过修改扰动检验函数参数,以利用传播的接触集。

英文摘要:

We give a simplified presentation of the obstacle problem approach to stochastic homogenization for elliptic equations in nondivergence form. Our argument also applies to equations which depend on the gradient of the unknown function. In the latter case, we overcome difficulties caused by a lack of estimates for the first derivatives of approximate correctors by modifying the perturbed test function argument to take advantage of the spreading of the contact set.
