英文摘要:
We consider the problem of superhedging under volatility uncertainty for an investor allowed to dynamically trade the underlying asset, and statically trade European call options for all possible strikes with some given maturity. This problem is classically approached by means of the Skorohod Embedding Problem (SEP). Instead, we provide a dual formulation which converts the superhedging problem into a continuous martingale optimal transportation problem. We then show that this formulation allows us to recover previously known results about lookback options. In particular, our methodology induces a new proof of the optimality of Az\\\'{e}ma-Yor solution of the SEP for a certain class of lookback options. Unlike the SEP technique, our approach applies to a large class of exotics and is suitable for numerical approximation techniques.

中文摘要:
我们考虑在波动不确定性下,允许投资者动态交易标的资产,并静态交易欧洲看涨期权,以获得给定到期日的所有可能冲击的问题。这个问题的经典方法是Skorohod嵌入问题(SEP)。相反,我们提供了一个对偶公式,将超边问题转化为连续鞅最优运输问题。然后我们证明,这个公式允许我们恢复以前已知的关于回望选项的结果。特别是,我们的方法对一类回望选项的SEP的Az\\\'{e}ma Yor解的最优性给出了一个新的证明。与SEP技术不同,我们的方法适用于一大类外显子,并且适用于数值近似技术。
