This is one chapter in a series on Mathematical Quantum Field Theory. The previous chapter is 9. Propagators. The next chapter is 11. Reduced phase space. 10. Gauge symmetries An infinitesimal gauge symmetry of a Lagrangian field theory (def. 10.3 below) is a infinitesimal symmetry of the Lagrangian which may be freely parameterized, hence “gauged”, […]
