摘要翻译:
本文研究了当大偏差理论应用于Heston模型中的某一期权定价公式时可能出现的与本质光滑性有关的问题。根据这个问题,注释在\cite{FordeJacquier10}中推论2.4的证明中确定了一个缺口,并描述了如何规避它。这完成了引用{FordeJacquier10}中推论2.4的证明,从而完成了引用{FordeJacquier10}中主要结果的证明,该结果描述了Heston模型中隐含波动率微笑在远未成熟时的极限行为。

英文摘要:
This note studies an issue relating to essential smoothness that can arise when the theory of large deviations is applied to a certain option pricing formula in the Heston model. The note identifies a gap, based on this issue, in the proof of Corollary 2.4 in \cite{FordeJacquier10} and describes how to circumvent it. This completes the proof of Corollary 2.4 in \cite{FordeJacquier10} and hence of the main result in \cite{FordeJacquier10}, which describes the limiting behaviour of the implied volatility smile in the Heston model far from maturity.
