FIELD THEORY: A PATH INTEGRAL APPROACH (2ND EDITION)

"This book is well-written and very readable. The book is a self-consistent introduction to the path integral formalism and no prior knowledge of it is required, although the reader should be familiar with quantum mechanics. This book is an excellent guide for the reader who wants a good and detailed introduction to the path integral and most of its important application in physics. I especially recommend it for graduate students in theoretical physics and for researchers who want to be introduced to the powerful path integral methods."Mathematical Reviews"... this volume gives a clear and neat account by way of practical use. Accordingly, it will be a useful compact textbook for graduate students to learn quantum field theory by path integral approach, especially, to get quickly an overview of its technical side so as to know the applicability of its methods to various areas."Zentralblatt MATH
