In finance, Girsanov theorem is used each time one needs to derive an asset's or rate's dynamics under a new probability measure. The most well known case is moving from historic measure P to risk neutral measure Q which is done - in Black Scholes framework - via Radon–Nikodym derivative: where r denotes the ...

Webcalled the Girsanov Theorem provides the roadmap. Consider a stock price process, where Wt is a Brownian motion: dSt St = µdt +σdWt This gives the dynamics of the stock price under the true/physical measure. Under this measure, the expected return is µ and the variance of the return is σ2 (both annualized).

"WebSince the fractional Brownian motion is not a semi-martingale, the usual Ito calculus cannot be used to define a full stochastic calculus. However, in this work, we obtain the Itô formula, the Itô–Clark representation formula and the Girsanov theorem for the functionals of a fractional Brownian motion using the stochastic calculus of variations.
