To achieve this result, we analyze the Kantorovich potentials of the optimal plans, and we estimate the distance of any optimal plan from the regions where the cost is infinite.Mathematics, AppliedMathematicsmultimarginal optimal transportdensity functional theorykantorovich potentialmarginal optimal transportcoulombtext::journal::journal article::research article
