Girsanov's theorem.


n this section we obtain the inverse result to the statement ( Transformation of SDE under change of measure ). Suppose $W_{t}$ is a standard Brownian motion adapted to a filtration $\QTR{cal}{F}_{t}$ and the process $B_{t}$ is given by MATH where $\theta_{s}$ is some $\QTR{cal}{F}_{t}$ -adapted process. We wish to find a process $h_{t}$ , such that the $B_{t}$ is a standard Brownian motion with respect to the MATH defined according to the formula ( Definition of change of measure ).
