Relativistic Quantum Fields

Relativistic Quantum Fields

<DIV></DIV> <div>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.</DIV>
