Kleinert H. Path Integrals in Quantum Mechanics, Statistics, Polymer Physics, and Financial Markets

5th. (online) ed. - Berlin: Freie Universität, 2009. - 1640 p.The paperback version of the fourth edition of this book was sold out in Fall 2008. This gave me a chance to revise it at many places. In particular, I improved considerably Chapter 20 on financial markets and removed some technical sections of Chapter 5.Preface to Fourth Edition.
