摘要翻译:
我们给出了隐含波动率表示为局部波动率或随机波动率加权期望值的时间平均值的一个新的证明。通过这个证明,我们澄清了在Gatheral的原始推导中存在向前隐含方差的问题,Gatheral在他的《波动面》一书中引入了这种表示。

英文摘要:
We give a new proof of the representation of implied volatility as a time-average of weighted expectations of local or stochastic volatility. With this proof we clarify the question of existence of 'forward implied variance' in the original derivation of Gatheral, who introduced this representation in his book 'The Volatility Surface'.
