英文摘要:
We obtain a dual representation of the Kantorovich functional defined for functions on the Skorokhod space using quotient sets. Our representation takes the form of a Choquet capacity generated by martingale measures satisfying additional constraints to ensure compatibility with the quotient sets. These sets contain stochastic integrals defined pathwise and two such definitions starting with simple integrands are given. Another important ingredient of our analysis is a regularized version of Jakubowski\'s $S$-topology on the Skorokhod space.

中文摘要:
我们利用商集得到了Skorokhod空间上定义的Kantorovich泛函的对偶表示。我们的表示形式是由满足额外约束的鞅度量生成的Choquet容量,以确保与商集的兼容性。这些集合包含按路径定义的随机积分,并给出了以简单被积函数开始的两个此类定义。我们分析的另一个重要组成部分是Skorokhod空间上Jakubowski的$s$-拓扑的正则化版本。
