"Many interesting developments have taken place in quantum field theory (QFT) since the 1970's, and there is no better place to learn about them than this book. The author has been an active contributor to the field over the past four decades and he has produced a personal book based on his lectures over the years. Reading the table of contents virtually gives you vertigo because the depth and breadth of the topics covered is simply staggering.
The author provides one of the most elegant and concise presentations of the use of instantons in gauge theories that I have ever seen. This book is a must for anyone interested in learning about the developments in advanced field theory over the past few decades. It is pedagogical and deeply insightful presentation by one of the masters in the field."

"Aimed at advanced students as well as researchers, the book is a unique combination of a basic guide to modern quantum field theory and a manual of new research topics."
Gert Roepstorff (Aachen)
"In total, this book is an excellent addition to the textbooks on quantum field theories. It fills part of a gap between the standard education on field theories and actual research, and covers many topics rarely taught in courses."
Axel Maas, Mathematical Reviews
Devoted specifically to modern field theory, this is an indispensable book for graduate students and researchers in theoretical physics. It emphasizes nonperturbative phenomena and supersymmetry, and discusses various phases of gauge theories, extended objects and their quantization, and global supersymmetry from a modern perspective.
