Menger curvatures and $C^{1,α}$ rectifiability of measures (1908.11471v2)

Abstract: We further develop the relationship between $\beta$-numbers and discrete curvatures to provide a new proof that under weak density assumptions, finiteness of the pointwise discrete curvature $\operatorname{curv}^{\alpha}_{\mu;2}(x,r)$ at $\mu$- a.e. $x \in \mathbb{R}^{m}$ implies that $\mu$ is $C^{1,\alpha}$ $n$-rectifiable.
