我们证明,如果 $ngeq 1$、$Omegasubset mathbb R^{n+1}$ 是具有多孔边界的连通域,并且 $EsubsetpartialOmega$ 是一组有限且正的 Hausdorff $H^{n}$ 测度,其中调和测度 $omega$ 相对于 $H^{n}$ 绝对连续,则 $omega|_E$ 集中在 $n$ 可整流集上。
We show that if $ngeq 1$, $Omegasubset mathbb R^{n+1}$ is a connected domain with porous boundary, and $Esubset partialOmega$ is a set of finite and positive Hausdorff $H^{n}$-measure upon which the harmonic measure $omega$ is absolutely continuous with respect to $H^{n}$, then $omega|_E$ is concentrated on an $n$-rectifiable set.
