For all 1 m n 1 , we investigate the interaction of locally finite measures in R n with the family of m -dimensional Lipschitz graphs. For instance, we characterize Radon measures μ , which are carried by Lipschitz graphs in the sense that there exist graphs Γ 1 , Γ 2 , such that μ ( R n 1 Γ i ) = 0 , using only countably many evaluations of the measure. This problem in geometric measure theory was classically studied within smaller classes of measures, for example, for the restrictions of m -dimensional Hausdorff measure H m to E R n with 0 < H m ( E ) < . However, an example of Csörnyei, Käenmäki, Rajala, and Suomala shows that classical methods are insufficient to detect when a general measure charges a Lipschitz graph. To develop a characterization of Lipschitz graph rectifiability for arbitrary Radon measures, we look at the behavior of coarse doubling ratios of the measure on dyadic cubes that intersect conical annuli. This extends a characterization of graph rectifiability for pointwise doubling measures by Naples by mimicking the approach used in the characterization of Radon measures carried by rectifiable curves by Badger and Schul.

氡测量和 Lipschitz 图

对所有人 1 n - 1 ,我们研究了局部有限测度的相互作用 电阻 n 与家人 维 Lipschitz 图。例如,我们描述氡测量 μ ,在存在图的意义上,它们由 Lipschitz 图携带 Γ 1 , Γ 2 , 以至于 μ ( 电阻 n 1 Γ 一世 ) = 0 ,仅使用可数的多个评估。几何测度理论中的这个问题在较小的测度类别中进行了经典的研究,例如,对于 维豪斯多夫测度 H 电阻 n 0 < H ( ) < . 然而,Csörnyei、Käenmäki、Rajala 和 Suomala 的一个例子表明,经典方法不足以检测一般度量何时对 Lipschitz 图充电。为了开发任意氡测量的 Lipschitz 图可修正性的特征,我们研究了与圆锥环相交的二元立方体上测量的粗倍率的行为。这通过模仿由 Badger 和 Schul 对可整流曲线所承载的氡量度进行表征所使用的方法,扩展了 Naples 对逐点加倍措施的图可整流性的表征。
