英文摘要:
A small-time Edgeworth expansion of the density of an asset price is given under a general stochastic volatility model, from which asymptotic expansions of put option prices and at-the-money implied volatilities follow. A limit theorem for at-the-money implied volatility skew and curvature is also given as a corollary. The rough Bergomi model is treated as an example.

中文摘要:
在一般随机波动率模型下,给出了资产价格密度的一个小时间Edgeworth展开式,在此基础上,看跌期权价格和货币隐含波动率的渐近展开式。作为推论,还给出了在货币条件下隐含波动率偏斜和曲率的极限定理。以粗糙Bergomi模型为例。
