This book is a modern pedagogic introduction to the ideas and techniques of quantum field theory. After a brief overview of particle physics and a survey of relativistic wave equations and Lagrangian methods,the quantum theory of scalar and spinor fields, and then of gauge fields,is developed The emphasis throughout is on functional methods,which have played a large part in modern field theory. The book concludes with a brief survey of `topological' objects in field theory and,new to this edition,a chapter devoted to supersymmetry. 此书为英文版! 本书是一本关于量子场论供大家参考。
