they are characterized equivalently by a no-crossing property of their support, as simultane- ous optimizers for a class of bivariate transport cost functions with a spence–mirrlees property, and by an order-theoretic minimality prop- erty. left-monotone transports are unique if μ is atomless, but not
, t) are of left-curtain type, if and only if μ , . . . , μn have a specific order property. the general analysis of the transport problem also gives rise to a strong duality result and a description of its polar sets. finally, we study a variant where the intermediate marginals μ , . . . , μn− are not...
