This textbook addresses graduate students starting to specialize in theoretical physics. It provides didactic introductions to the main topics in the theory of fields, while taking into account the contemporary view of the subject. The student will find concise explanations of basic notions essential for applications of the theory of fields as well as for frontier research in theoretical physics. One third of the book is devoted to classical fields. Each chapter contains exercises of varying degree of difficulty with hints or solutions, plus summaries and worked examples as useful. It aims to deliver a unique combination of classical and quantum field theory in one compact course.

Offers a unique combination of classical and quantum field theory in one compact course Treats a variety of topics only touched briefly in other quantum field textbooks Complete updated and expanded with several new sections, as well as further exercises and solutions Includes supplementary material: sn.pub/extras
