Two Sufficient Conditions for Rectifiable Measures
نویسندگان
چکیده
We identify two sufficient conditions for locally finite Borel measures on R to give full mass to a countable family of Lipschitz images of R. The first condition, extending a prior result of Pajot, is a sufficient test in terms of L affine approximability for a locally finite Borel measure μ on R satisfying the global regularity hypothesis lim sup r↓0 μ(B(x, r))/r <∞ at μ-a.e. x ∈ R to be m-rectifiable in the sense above. The second condition is an assumption on the growth rate of the 1-density that ensures a locally finite Borel measure μ on R with lim r↓0 μ(B(x, r))/r =∞ at μ-a.e. x ∈ R

Multiscale Analysis of 1-rectifiable Measures: Necessary Conditions
We repurpose tools from the theory of quantitative rectifiability to study the qualitative rectifiability of measures in R, n ≥ 2. To each locally finite Borel measure μ, we associate a function J̃2(μ, x) which uses a weighted sum to record how closely the mass of μ is concentrated near a line in the triples of dyadic cubes containing x. We show that J̃2(μ, ·) < ∞ μ-a.e. is a necessary condition ...
متن کاملLp-ESTIMATES FOR THE VARIATION FOR SINGULAR INTEGRALS ON UNIFORMLY RECTIFIABLE SETS
The L (1 < p < ∞) and weak-L estimates for the variation for CalderónZygmund operators with smooth odd kernel on uniformly rectifiable measures are proven. The L boundedness and the corona decomposition method are two key ingredients of the proof.

Let A be a compact set in Rp of Hausdorff dimension d. For s ∈ (0, d), the Riesz s-equilibrium measure μs is the unique Borel probability measure with support in A that minimizes Is(μ) := " 1 |x − y|s dμ(y)dμ(x) over all such probability measures. If A is strongly (Hd , d)-rectifiable, then μs converges in the weak-star topology to normalized d-dimensional Hausdorff measure restricted to A as s...
متن کاملRectifiable oscillations of radially symmetric solutions of p-Laplace differential equations
Let Ω = {x ∈ RN : r0 |x| < 1} with N 2 and r0 ∈ (0,1) . We study a kind of geometric oscillatory and asymptotic behaviour near |x| = 1 of all radially symmetric solutions u = u(x) of the p -Laplace partial differential equation (P) : −div(|∇u| p−2∇u) = f (|x|)|u|p−2u in Ω , u = 0 on |x| = 1 for p > 1 . Necessary and sufficient conditions on the coefficient f (|x|) are given such that u(x) oscil...

In the present paper a definition of relative content is given which makes it possible to prove that if P and Px are subject to certain conditions, the content of K, relative to a certain non-additive function of rectangles derived from P, exists equal to the double integral on the left of (1) and also equal t...
