"Complete, systematic, self-contained...the usefulness and scope of application of such a work is enormous...combines thorough knowledge with a high degree of didactic ability and a delightful style."--Mathematical Reviews
In a relatively simple presentation that remains close to familiar concepts, this text for upper-level undergraduates and graduate students introduces the modern developments of quantum field theory. Starting with a review of the one-particle relativistic wave equations, it proceeds to a second-quantized description of a system of n particles, examines the restriction that symmetries impose on Lagrangians, and analyzes simple models of field theories. Additional topics include the Feynman-Dyson perturbation treatment of relativistic field theories, the formulation of field theory in the Heisenberg picture, the axiomatic formulation of field theory, and dispersion theoretic methods. 1961 ed.
