Extension of the Predictable Integrands,In this chapter, we show that the definition of the stochastic integral can be extended to a larger class of integrands than the predictable ones, when either a mild condition on the Doléans measure . is satisfied or . is continuous.

Quadratic Variation Process,For the remainder of this book, we shall only consider integrators . which are . local martingales. By Proposition 1.9 these are automatically local .-martingales. A more extensive treatment, encompassing right continuous integrators would require more elaborate considerations which are not suitable for inclusion in this short book.

The Ito Formula,rst proved it for the special case of integration with respect to Brownian motion. The essential aspects of Itô’s formula are conveyed by the following. If . is a continuous local martingale and . is a twice continuously differentiable real-valued function on ., then the Itô formula for .(..) is
