Abstract

Abstract We give an infinite-dimensional Lie group from which a group approach to quantization (GAQ) derives a Gupta-Bleuler-like quantization for the electromagnetic field. The incorporation into the group law of the gauge transformation properties of A μ ( x), A μ ( x) → A μ ( x) + ∂ μ φ, requires a non-conventional generator which is related to the BRST charge.
