摘要:

该文研究了形如-div(A(x/ε,x/ε)▽uε)=f(x)的椭圆重复齐次化问题解的收敛性, 得到了 Dirichlet 边界条件下解在 W01,p空间的收敛率. 证明所用的技巧是基于得到算子格林函数的估计.

关键词: 齐次化, 收敛性, 格林函数

Abstract:

In this paper, we study the convergence of solutions for the elliptic reiterated homogenization problem of the form -div(A(x/ε,x/ε)▽uε)=f(x). We obtain the convergence rates in W01,p for solutions with Dirichlet boundary conditions. Our techniques are based on obtaining estimates for Green functions of the operators.

Key words: Homogenization, Convergence, Green functions
