Semimartingales and Stochastic Differentials,h respect to local ..-martingales. This is most naturally given by the concept of a semimartingale. In the next chapter and in chapter 10 we shall see that semimartingales are very flexible also in other respects.

The Special Role of Brownian Motion,e deals with what we view as the most important result on Brownian motion (besides Wiener’s existence theorem) namely P. Levy’s characterization by means of quadratic variation. The theorem of K. Dambis, L.E. Dubins and G. Schwarz in section 9.2 tells us that every a.s. continuous local martingale i

Predictability,in a (local) ..-sense. The measure which governs this ..-convergence is the “Föllmer-Doleans measure” on ℝ. × Ω given by d[M]. dℙ(ω) where [M] is the increasing (quadratic variation) process of the integrator M.

Processes and Filtrations, X may also be viewed as a single function of two variables t and ω. Stopping times and filtrations are introduced in order to deal with measurability questions arising from the interplay between t an ω.
