Necessary Condition for Rectifiability Involving Wasserstein Distance W2

  title={Necessary Condition for Rectifiability Involving Wasserstein Distance W2},
  author={Damian Dkabrowski},
A Radon measure μ is n-rectifiable if μ ≪ H n and μ-almost all of supp μ can be covered by Lipschitz images of R. In this paper we give a necessary condition for rectifiability in terms of the so-called α2 numbers – coefficients quantifying flatness using Wasserstein distance W2. In a recent article we showed that the same condition is also sufficient for rectifiability, and so we get a new characterization of rectifiable measures. 
Cones, rectifiability, and singular integral operators
Let μ be a Radon measure on R. We define and study conical energies Eμ,p(x, V, α), which quantify the portion of μ lying in the cone with vertex x ∈ R , direction V ∈ G(d, d−n), and aperture α ∈ (0,Expand
Identifying 1-rectifiable measures in Carnot groups
We continue to develop a program in geometric measure theory that seeks to identify how measures in a space interact with canonical families of sets in the space. In particular, extending a theoremExpand
An $\alpha$-number characterization of $L^{p}$ spaces on uniformly rectifiable sets
We give a characterization of $L^{p}(\sigma)$ for uniformly rectifiable measures $\sigma$ using Tolsa's $\alpha$-numbers, by showing, for $1<p<\infty$ and $f\in L^{p}(\sigma)$, that \[ \lVertExpand


Multiscale Analysis of 1-rectifiable Measures II: Characterizations
Abstract A measure is 1-rectifiable if there is a countable union of finite length curves whose complement has zero measure. We characterize 1-rectifiable Radon measures μ in n-dimensional EuclideanExpand
Characterization of rectifiable measures in terms of 𝛼-numbers
We characterize Radon measures $\mu$ in $\mathbb{R}^{n}$ that are $d$-rectifiable in the sense that their supports are covered up to $\mu$-measure zero by countably many $d$-dimensional LipschitzExpand
Sufficient Condition for Rectifiability Involving Wasserstein Distance $$W_2$$
A Radon measure $\mu$ is $n$-rectifiable if it is absolutely continuous with respect to $\mathcal{H}^n$ and $\mu$-almost all of $\text{supp}\,\mu$ can be covered by Lipschitz images ofExpand
Generalized rectifiability of measures and the identification problem
One goal of geometric measure theory is to understand how measures in the plane or a higher dimensional Euclidean space interact with families of lower dimensional sets. An important dichotomy arisesExpand
Analysis of and on uniformly rectifiable sets
The notion of uniform rectifiability of sets (in a Euclidean space), which emerged only recently, can be viewed in several different ways. It can be viewed as a quantitative and scale-invariantExpand
Uniform rectifiability, Calderón–Zygmund operators with odd kernel, and quasiorthogonality
In this paper we study some questions in connection with uniform rectifiability and the $L^2$ boundedness of Calderon-Zygmund operators. We show that uniform rectifiability can be characterized inExpand

In some former works of Azzam and Tolsa it was shown that $n$-rectifiability can be characterized in terms of a square function involving the David-Semmes $\beta_2$ coefficients. In the present paperExpand
Rectifiable sets and the Traveling Salesman Problem
Let K c C be a bounded set. In this paper we shall give a simple necessary and sufficient condit ion for K to lie in a rectifiable curve. We say that a set is a rectifiable curve if it is the imageExpand
