A universal support theorem for 1-Wasserstein optimal transport

Ze-An Ng

We show that every optimal transport plan for the $1$ -Wasserstein distance in $R^{n}$ is supported on a closed $n + 1$ rectifiable set. In particular, the support of any optima…

On equality of the $L^{\infty}$ norm of the gradient under the Hausdorff and Lebesgue measure

Ze-An Ng

Let $Ω$ be an open subset of $R^{n}$ , and let $f : Ω \to R$ be differentiable $H^{k}$ -almost everywhere, for some nonnegative integer $k < n$ , where $\mathcal H^…
