英文摘要：
  We consider a financial market with one riskless and one risky asset. The super-replication theorem states that there is no duality gap in the problem of super-replicating a contingent claim under transaction costs and the associated dual problem. We give two versions of this theorem. The first theorem relates a num\\\'eraire-based admissibility condition in the primal problem to the notion of a local martingale in the dual problem. The second theorem relates a num\\\'eraire -free admissibility condition in the primal problem to the notion of a uniformly integrable martingale in the dual problem.

中文摘要：
我们考虑一个只有一种无风险资产和一种风险资产的金融市场。超级复制定理表明，在交易费用下的超级复制未定权益问题和相关对偶问题中不存在对偶缺口。我们给出了这个定理的两个版本。第一个定理将原问题中基于数值的可容许性条件与对偶问题中的局部鞅概念联系起来。第二个定理将原问题中的无干扰可容许条件与对偶问题中的一致可积鞅的概念联系起来。
