Quantum field theory : a modern introduction

This is the only up-to-date introductory textbook on the modern approach to quantum field theory, intended for the graduate course on the subject taught in all graduate physics programmes with interests in high-energy physics. It is also the first textbook to include discussions of topics that have become so vital to a modern treatment of GFT, such as critical phenomena, lattice gauge theory, supersymmetry, quantum gravity, supergravity, and superstrings. Over 260 exercises are included.
