摘要

本文证明了若 μ\muRd\mathbb R^d 中的有限 Radon 测度,且是 nn 维可求长的,并且 1p21\leq p\leq 2,则有 \int_0^\infty \beta_{\mu,p}^n(x,r)^2\,\frac{dr}r<\infty \quad {对 $\mu$ 几乎处处的 $x\in\mathbb R^d$ 成立}, 其中 βμ,pn(x,r)=infL(1rnBˉ(x,r)(dist(y,L)r)pdμ(y))1/p,\beta_{\mu,p}^n(x,r) = \inf_L (\frac1{r^n} \int_{\bar B(x,r)} (\frac{\mathrm dist(y,L)}{r})^p\,d\mu(y))^{1/p}, 下确界取遍所有 nn 维平面 LRdL\subset \mathbb R^d。系数 βμ,pn\beta_{\mu,p}^n 与 David 和 Semmes 在所谓一致 nn 维可求长性背景下考虑的系数相同。本文还证明了涉及 Wasserstein 距离 W1W_1 某种变体的其他系数给出的 nn 维可求长性的类似必要条件。

备注

In the previous version there was a gap in the proof of Main Lemma 2.1 because of an incorrect statement just above (2.22). Now this gap is corrected. This has required to change the definition of the approximating measure in Section 2. The new arguments for Main Lemma 2.1 are along the same lines as in the previous version of the paper
