A regularized and renormalized massive-vector-field theory in a Friedmann space-time is formulated. A comparison with the scalar (and spinor) cases is performed. This formulation may be of some relevance for the very early phases of the expansion of the Universe, in relation with the possibility that gauge field quanta are created because of curvature variation.

Abstract
A regularized and renormalized massive-vector-field theory in a Friedmann space-time is formulated. A comparison with the scalar (and spinor) cases is performed. This formulation may be of some relevance for the very early phases of the expansion of the Universe, in relation with the possibility that gauge field quanta are created because of curvature variation.
