Quantum Field Theory
"Marked by its astute choice of topics as well as by the clarity with which they are expounded, it is akin to a toolbox for students of modern quantum field theory...a very interesting and original textbook."  Pierre Raymond, Science"...nicely self-contained text for physicists with little or no a priori knowledge of quantum field theory....I recommend the book without hesitation to QFT lecturers, who will certainly find it helpful and will no doubt enjoy some of the occasional pedagogical innovations."   Jean Zinn-Justin, Physics World"...a personal, but by no means an idiosyncratic book, to be recommended in the highest terms to students of particle physics."   Lewis Ryder, The Times Higher Education Supplement"Brown's book is distinguished by the care and clarity with which he treats the topics discussed. I sense that he has rethought everything afresh, starting from basic principles; his descriptions of topics are almost invariably better than those of earlier authors."  O.W. Greenberg, Physics Today"...anyone who masters the greater part of [Quantum Field Theory] will be very well-equipped...consistent in its writing...with plenty of substantial, but doable, exercises to provide markers on progress as well as avenues for further instruction."   Mathematical Reviews"...This is a very interesting and original textbook...the style of presentation is crisp, and the book is sprinkled with the author's understated humor. The technical discussions are lucid, compact, and easy to follow...any student who masters the techniques expounded here will emerge with a thorough knowledge of quantum field theory.  I strongly recommend this book to whoever aspires to become either a particle or a condensed matter physicist."   Science"...very readable...an excellent introduction to modern techniques of quantum field theory..."   Physics in Canada
