Absolute Continuity of Wasserstein Barycenters Over Alexandrov Spaces
Published online by Cambridge University Press: 20 November 2018
Abstract
In this paper, we prove that on a compact, $n$-dimensional Alexandrov space with curvature at least −1, the Wasserstein barycenter of Borel probability measures ${{\mu }_{1}},\ldots ,{{\mu }_{m}}$ is absolutely continuous with respect to the $n$-dimensional Hausdorff measure if one of them is.
