This advanced volume is based on graduate courses and summer schools given over a number of years by the author. It approaches the subject in terms of path and functional integrals. A Euclidean metric has been adopted and the language of partition and correlation functions is used. Renormalization and the renormalization group are discussed. A major part of the book is devoted to critical phenomena before concluding with a discussion of the role of instantons in quantum field theory. ER -
