具有快速振荡势的椭圆均匀化中本征值和本征函数的估计

Estimates of eigenvalues and eigenfunctions in elliptic homogenization with rapidly oscillating potentials

Yiping Zhang

摘要:

本文研究了一类具有快速振荡周期系数和快速振荡周期势的二阶椭圆型方程的$H^1$收敛速度和Dirichlet特征值以及Dirichlet特征函数法向导数的界. $H^1$的收敛速度依赖于Dirichlet校正和一阶校正的振荡电位。对于Dirichlet条件下的解,其界依赖于$H^1$中的一个$O(\varepsilon)$估计.

英文摘要:

In this paper, for a family of second-order elliptic equations with rapidly oscillating periodic coefficients and rapidly oscillating periodic potentials, we are interested in the $H^1$ convergence rates and the Dirichlet eigenvalues and bounds of the normal derivatives of Dirichlet eigenfunctions. The $H^1$ convergence rates rely on the Dirichlet correctors and the first-order corrector for the oscillating potentials. And the bound results rely on an $O(\varepsilon)$ estimate in $H^1$ for solutions with Dirichlet condition.
