自然增长条件下椭圆型方程组的边界正则性

Boundary regularity for elliptic systems under a natural growth condition

Lisa Beck

摘要:

本文考虑一类二阶非线性椭圆型方程组的弱解$u \in u_0 + W^{1,2}_0(Ω,R^N) \cap L^{\infty}(Ω,R^N)$,其中$- div a (\cdot, u, Du) = b(\cdot,u,Du)$在$Ω$中具有满足自然增长条件的非齐次项.在尺寸$n \in \{2,3,4\}$,我们表明,$\mathcal{H}^{n-1}$ -几乎每一个边界点是$Du$的正则点,只要边界数据和系数是足够光滑的。

英文摘要:

We consider weak solutions $u \in u_0 + W^{1,2}_0(Ω,R^N) \cap L^{\infty}(Ω,R^N)$ of second order nonlinear elliptic systems of the type $- div a (\cdot, u, Du) = b(\cdot,u,Du)$ in $Ω$ with an inhomogeneity satisfying a natural growth condition. In dimensions $n \in \{2,3,4\}$ we show that $\mathcal{H}^{n-1}$-almost every boundary point is a regular point for $Du$, provided that the boundary data and the coefficients are sufficiently smooth.
