The Global Approach to Quantum Field Theory

by Bryce S. DeWitt

Book Overview

The book shows how classical field theory, quantum mechanics, and quantum field theory are related. The
description is global from the outset. Quantization is explained using the Peierls bracket rather than the Poisson bracket. This allows one to deal immediately with observables, bypassing the canonical formalism of constrained Hamiltonian systems and bigger-than-physical Hilbert (or Fock) spaces. The Peierls bracket leads directly to the Schwinger...
