In the first part of this paper, the relativistic significance of the projective curvature tensor Wh<jk is discussed. It is found that the vanishing of the divergence of this tensor in an electrovac universe implies a purely electric field. By breaking Whijk into its antisymmetric and symmetric part
On pseudo-Riemannian conformal 4-manifolds we give a conformally invariant extension of the Maxwell operator on 1-forms. This recovers an invariant gauge operator due to Eastwood and Singer. We show that, in the case of Riemannian signature, the extension is in an appropriate sense injectively ellip
