英文摘要:
In this paper, we introduce and develop the theory of semimartingale optimal transport in a path dependent setting. Instead of the classical constraints on marginal distributions, we consider a general framework of path dependent constraints. Duality results are established, representing the solution in terms of path dependent partial differential equations (PPDEs). Moreover, we provide a dimension reduction result based on the new notion of \"semifiltrations\", which identifies appropriate Markovian state variables based on the constraints and the cost function. Our technique is then applied to the exact calibration of volatility models to the prices of general path dependent derivatives.

中文摘要:
本文引入并发展了路径相关环境下的半鞅最优运输理论。我们考虑的是路径依赖约束的一般框架,而不是对边际分布的经典约束。建立了对偶结果,用路径相关偏微分方程(PPDE)表示解。此外,我们提供了一个基于“半过滤”新概念的降维结果,该结果基于约束和代价函数识别适当的马尔可夫状态变量。然后,我们的技术被应用于波动率模型对一般路径依赖衍生品价格的精确校准。
