英文摘要：
Using classical Taylor series techniques, we develop a unified approach to pricing and implied volatility for European-style options in a general local-stochastic volatility setting. Our price approximations require only a normal CDF and our implied volatility approximations are fully explicit (ie, they require no special functions, no infinite series and no numerical integration). As such, approximate prices can be computed as efficiently as Black-Scholes prices, and approximate implied volatilities can be computed nearly instantaneously.

中文摘要：
利用经典的泰勒级数方法，我们在一般的局部随机波动率环境下，建立了欧式期权定价和隐含波动率的统一方法。我们的价格近似只需要一个正常的CDF，我们的隐含波动率近似是完全明确的（即，它们不需要特殊函数、无限级数和数值积分）。因此，近似价格可以像Black-Scholes价格一样有效地计算，近似隐含波动率几乎可以在瞬间计算。
