The reason is that the condition that E(R 0 qu dBu) be uniformly integrable on the entire [0,¥) is either hard to … WebFor Brownian motion, the topics of local time, reflected Brownian motion, and time change are discussed. New to the second edition are a discussion of the Cameron–Martin–Girsanov transformation and a final chapter which provides an introduction to stochastic differential equations, as well as many exercises for classroom use.
WebGirsanov's theorem is important in the general theory of stochastic processes since it enables the key result that if Q is a measure absolutely continuous with respect to P then every P-semimartingale is a Q-semimartingale. Statement of theorem. We state the theorem first for the special case when the underlying stochastic process is a Wiener ...
