Before revision: By Gyongy's theorem, a local and stochastic volatility  model is calibrated to the market prices of all  call options with positive maturities and strikes if its local volatility function is equal to the ratio of the Dupire local volatility function over the root conditional mean square of the stochastic volatility factor given the spot value.
After revision: By Gyongy's theorem, a local and stochastic volatility (LSV) model is calibrated to the market prices of all call options with positive maturities and strikes if its local volatility function is equal to the ratio of the Dupire local volatility function over the root conditional mean square of the stochastic volatility factor given the spot value.
