From the reviews:
"There is, as the author of this book points out, a shortage of books of problems on quantum field theory. This one is based on exercises set to undergraduate and graduate students of the University of Belgrade. There are 64 pages of problems and the solutions occupy a further 171 pages. There is a bibliography and an index. … The book would serve well to accompany an introductory course on QFT." (Lewis H. Ryder, Mathematical Reviews, Issue 2007 c)
"The book provides the reader with about 200 problems on different topics in quantum field theory … . The material covered and the level of exposition make the book typically appropriate for graduate and undergraduate students in physics. It is actually one of the first problem books in quantum field theory, and can be very useful students both following a course and studying on their own." (Bassano Vacchini, Zentralblatt MATH, Vol. 1102 (4), 2007)
The "Problem Book in Quantum Field Theory" contains about 200 problems with solutions or hints that help students to improve their understanding and develop skills necessary for pursuing the subject. It deals with the Klein-Gordon and Dirac equations, classical field theory, canonical quantization of scalar, Dirac and electromagnetic fields, the processes in the lowest order of perturbation theory, renormalization and regularization. The solutions are presented in a systematic and complete manner. The material covered and the level of exposition make the book appropriate for graduate and undergraduate students in physics, as well as for teachers and researchers. The new edition is a corrected paperback edition for students.
