A concise good book

This book is suitable for those meeting the subject for the first time- graduate students in theoretical physics take note. Divided into two parts: Part 1 on General Field Theory and part 2 on Advanced Field theory, it treats both parts competently. Part 2 kicks off with a good discussion of Schwinger's Action Principle and includes a very good treatment of Path Integrals. Part 1 is mainly the usual canonical field theory, Feynman diagrams, QED, but also includes the application of the diagrammatic techniques to the many-body system. This addition is nonconventional and is welcome. However two cautionary remarks: Calculations are sparse and there are no problems at the ends of the chapters. You need to rectify that by resorting to a text like the one by Peskin and Scheroder. Secondly there are quite a number of typographical erros...not very serious and might hopefully be eliminated in future editions. I like this book!

A good concise book

This book is suitable for those meeting the subject for the first time- graduate students in theoretical physics take note. It has two parts: Part 1 is the conventional canonical perturbation diagrammatic Feynman-Dyson technique with a welcome additional nonconventional application to the many-body system. Part 2 is advanced field theory kicking off with a beautiful discussion of Schwinger's Action Principle and includung a clear exposition of Path Integrals. On the whole this book is concise and well written. Two cautionary remarks are however in order: Not many calculations are there and no problems at the ends of chapters. So you might need to resort to a companion book like that by Peskin and Schroeder. Also there are quite anumber of typographical errors- not serious and might hopefully be eliminated in future editions. I like this book.
