Detailed Description

Black volatility curve modelled as variance curve.

This class calculates time-dependent Black volatilities using as input a vector of (ATM) Black volatilities observed in the market.

The calculation is performed interpolating on the variance curve. Linear interpolation is used as default; this can be changed by the setInterpolation() method.

For strike dependence, see BlackVarianceSurface.

Possible enhancements

check time extrapolation
