二阶强椭圆型方程组的格林函数估计

The Green function estimates for strongly elliptic systems of second order

Steve Hofmann, Seick Kim

摘要:

本文在区域$Ω\subseteq \mathbb{R}^n$,$n \geq 3$中,在系统解满足De Giorgi-Nash型局部Hölder连续估计的条件下,建立了散度型二阶强椭圆方程组基本解和Green矩阵的存在性和逐点估计.特别是,我们的结果适用于扰动的对角系统,因此特别是复杂的扰动一个单一的真正的方程。

英文摘要:

We establish existence and pointwise estimates of fundamental solutions and Green's matrices for divergence form, second order strongly elliptic systems in a domain $Ω\subseteq \mathbb{R}^n$, $n \geq 3$, under the assumption that solutions of the system satisfy De Giorgi-Nash type local Hölder continuity estimates. In particular, our results apply to perturbations of diagonal systems, and thus especially to complex perturbations of a single real equation.
