英文摘要:
We study the optimal transport between two probability measures on the real line, where the transport plans are laws of one-step martingales. A quasi-sure formulation of the dual problem is introduced and shown to yield a complete duality theory for general marginals and measurable reward (cost) functions: absence of a duality gap and existence of dual optimizers. Both properties are shown to fail in the classical formulation. As a consequence of the duality result, we obtain a general principle of cyclical monotonicity describing the geometry of optimal transports.

中文摘要:
我们研究了实线路上两个概率测度之间的最优运输,其中运输计划是一步鞅定律。本文介绍了对偶问题的一个拟确定公式,并证明了它对一般边际和可测报酬(代价)函数给出了一个完整的对偶理论:不存在对偶缺口和对偶优化器。这两个性质在经典公式中都被证明是失败的。作为对偶结果的结果,我们得到了描述最优传输几何的循环单调性的一般原理。
