基于尺度积分的次微分包含的随机均匀化

Stochastic homogenization of subdifferential inclusions via scale integration

Marco Veneroni

摘要:

本文研究了系统-div σ^ε= f^εσ^ε \in \partial <$^ε(\nabla u^ε)的随机均匀化问题,其中(<$^ε)是一个凸平稳随机场序列,具有p-增长.证明了解序列(σ^ε,u^ε)收敛于具有相同次微分结构的确定性系统的解.这个证明依赖于Birkhoff的遍历定理、凸函数的次微分的最大单调性和A.维辛汀

英文摘要:

We study the stochastic homogenization of the system -div σ^ε= f^εσ^ε\in \partial ϕ^ε(\nabla u^ε), where (ϕ^ε) is a sequence of convex stationary random fields, with p-growth. We prove that sequences of solutions (σ^ε,u^ε) converge to the solutions of a deterministic system having the same subdifferential structure. The proof relies on Birkhoff's ergodic theorem, on the maximal monotonicity of the subdifferential of a convex function, and on a new idea of scale integration, recently introduced by A. Visintin.
