We explain how properties of a local martingale are related to those of its quadratic variation. Finally, we introduce continuous semimartingales and their quadratic variation processes.

We then discuss Gaussian spaces and Gaussian processes, and we establish the fundamental properties concerning independence and conditioning in the Gaussian setting. We finally introduce the notion of a Gaussian white noise, which is used to give a s

Going from pre-Brownian motion to Brownian motion requires the additional property of continuity of sample paths, which is derived here via the classical Kolmogorov lemma. The end of the chapter discusses several properties

In a second step, we develop the theory of continuous time martingales, and, in particular, we derive regularity results for sample paths of marting
