In this chapter, we will obtain Girsanov Theorem and its generalizations by Meyer. Let M be a martingale on and let be another probability measure on absolutely continuous w.r.t. Then as noted in Remark 4.26, M is a semimartingale on We will obtain a decomposition of M into N and B, where N is a martingale. This result for Brownian motion was due to Girsanov, and we will also present the generalizations due to Meyer.
