If you found these forward references a bit unsettling, it is quite reasonable to first read Chapter 2 sections , then read Chapter 1, and then finish up with canonical Brownian motion section at the end of Chapter 2. Chapter 3 is a wonderful treatment of Markov processes and requires that the reader have an appreciation of the classical theory of Markov chains.
In the first section of Chapter 3, the basic theory of operator semigroups is covered and the authors prove the famous Hille-Yosida Theorem. The next section covers the 'base case' of operator semigroups. Rogers and Williams refer to these as Feller-Dynkin semigroups. Each Feller-Dynkin semigroup is shown to be realized by strong Markov process.
Continuous Levy processes are then characterized as a nice application of the Feller-Dynkin theory. The highlight of the next section is the Feynmac-Kac formulas. These are presented from the Markov process point of view computing generators of transformed Markov processes , not from the usual PDEs point of view.
Cambridge Mathematical Library Diffusions, Markov Processes, and Martingales: Foundations Volume 1
Since the authors don't have Ito's Rule available in this first volume, they establish Feynman-Kac using the theory of additive functionals. The final sections of the book deal with Markov processes with values in a countable state space. Ray processes and the Martin boundary are introduced, however as I began read this material, I felt that the authors believed that I already knew why Ray Theory is so important.
I felt this last material would have been a bit better motivated with more of a tie-in to the theory of harmonic functions and the Dirichlet problem. However, the proof of Ray's Theorem is very elegant and really solidifies the reader's understanding of the Hille-Yosida Theorem.
Several of the sections wrap up with a small set of exercises. There are also exercises sprinkled throughout the text several of which the authors plead with you to work through.
The exercises have been thoughtfully selected and reinforce the material. January 15, - Published on Amazon. This book and its companion volume are a well organized and relatively easy-to-read introduction to a wide variety of ideas in stochastic processes. It is not only a great reference I always keep it on my desk but it also has a solid expositional style that fully motivates concepts as they are introduced.
The Ito Calculus volume goes deeper than a number of other books on topic including information on integration wrt to a general semimartingale instead of just BM and even an introduction to stochastic calculus on manifolds. August 17, - Published on Amazon. Everything about X - every Wednesday.

This is a great book. It is not difficult to read. The style is very informal and at times actually humourous. It does not follow the definition-lemma-proof way of doing things at the expense of leaving simple definitions out, but these can be easily found somewhere else.

The book contains an enormous amount of information, and the authors are clearly men of great knowledge and depth. The book is very nicely produced from a 1st edition by Cambridge U Press. Very clearly printed, and at a low p This is a great book. Very clearly printed, and at a low price for the volume. I highly recommend both volumes to anyone who works in stochastic processes, or mathematical finance assuming one wants to learn things, rather than just talk about them.
