<p>The authors of this classic physics text develop a canonical field theory and relate it to Feynman graph expansion. With graph analysis, they explore the analyticity properties of Feynman amplitudes to arbitrary orders, illustrate dispersion relation methods, and prove the finiteness of renormalized quantum electrodynamics to each order of the interaction. 1965 edition.</p>

<p>In this text the authors develop a propagator theory of Dirac particles, photons, and Klein-Gordon mesons and per- form a series of calculations designed to illustrate various useful techniques and concepts in electromagnetic, weak, and strong interactions. these include defining and implementing the renormalization program and evaluating effects of radia- tive corrections, such as the Lamb shift, in low-order calculations. The necessary background for the book is pro- vided by a course in nonrelativistic quantum mechanics at the general level of Schiff's text, QUANTUM MECHANICS.</p>

This classic physics text attests to the importance of Richard Feynman's graphs and rules of calculation, and it advises physicists to incorporate Feynman's calculations into their problem-solving methods for canonical quantum field theory. Written by a pair of prominent theoretical physicists, it is geared toward advanced undergraduate and graduate physics majors.Starting with an examination of general formalism, the treatment explores the Klein-Gordon field, second quantization of the Dirac field, quantization of the electromagnetic field, interacting fields, and vacuum expectation values and the scattering matrix. Additional subjects include perturbation theory, dispersion relations, and renormalization. Three appendixes supplement the text.
