This book is not a research monograph about Malliavin calculus with the latest results and the most sophisticated proofs. It does not contain all the results which are known even for the basic subjects which are addressed here. The goal was to give the largest possible variety of proof techniques. For instance, we did not focus on the proof of concentration inequality for functionals of the Brownian motion, as it closely follows the lines of the analog result for Poisson functionals. This book grew from the graduate courses I gave at Paris-Sorbonne and Paris-Saclay universities, during the last few years. It is supposed to be as accessible as possible for students who have knowledge of Ito calculus and some rudiments of functional analysis.
"For all the notions, precise definitions of the mathematical objects and complete proofs of the results are given; some examples are thoroughly studied. At the end of each chapter, the reader can also find some classical mathematical background. This book should prove useful for students and academic scholars wishing to get acquainted with Malliavin's calculus, and also for more advanced researchers interested by more recent applications."
