摘要:

设$Ω$是$\mathbb{R}^n$中具有$C^{1}$边界的有界区域,$u_λ$是$Ω$中具有特征值$λ$的Dirichlet Laplace特征函数.证明了$u_λ$的零集的$(n-1)$维Hausdorff测度不超过$C(Ω)\sqrtλ$ .这一结果对于具有$C^\infty$ -光滑边界的区域也是新的.

英文摘要:

Let $Ω$ be a bounded domain in $\mathbb{R}^n$ with $C^{1}$ boundary and let $u_λ$ be a Dirichlet Laplace eigenfunction in $Ω$ with eigenvalue $λ$. We show that the $(n-1)$-dimensional Hausdorff measure of the zero set of $u_λ$ does not exceed $C(Ω)\sqrtλ$. This result is new even for the case of domains with $C^\infty$-smooth boundary.
