The existence of a weak solution and the uniqueness in law are assumed for the equation, the coefficients and being generally -progressive processes. Any weak solution is called a -stock price and Girsanov Theorem jointly with the DDS Theorem on time changed martingales are applied to establish the probability distribution of in in the special case of a diffusion volatility A martingale option pricing method is presented.

A generic control variate method is proposed to price options under stochastic volatility models by Monte Carlo simulations. This method provides a constructive way to select control variates which are martingales in order to reduce the variance of unbiased option price estimators. We apply a singular and regular perturbation analysis to characterize the variance reduced by martingale control variates. This variance analysis is done in the regime where time scales of associated driving...
