Abstract:

A Dirichlet region for an optimal mass transportation problem is, roughly speaking, a zone in which the transportation cost is vanishing. We study the optimal transportation problem with an unknown Dirichlet region $\Sigma$ which varies in the class of closed connected subsets having prescribed $1$-dimensional Hausdorff measure. We show the existence of an optimal $\Sigma_{opt}$ and study some of its geometrical properties. We also present numerical computations which show the shape of $\Sigma_{opt}$ in some model examples.
