Abstract

We study optimal transport with a non-convex polyhedral target in Rn. The closure of the singular set is locally a smooth hypersurface outside a relatively closed set of Hausdorff dimension at most n-2. For partial transport between domains separated by a hyperplane, the source free boundary has the same regularity.
