Note on (conformally) semi-symmetric spacetimes
Ingemar Eriksson, José M. M. Senovilla
We provide a simple proof that conformally semi-symmetric spacetimes are actually semi-symmetric. We also present a complete refined classification of the semi-symmetric spacetimes…
Conserved Matter Superenergy Currents for Orthogonally Transitive Abelian G2 Isometry Groups
Ingemar Eriksson
In a previous paper we showed that the electromagnetic superenergy tensor, the Chevreton tensor, gives rise to a conserved current when there is a hypersurface orthogonal Killing v…
The Chevreton Tensor and Einstein-Maxwell Spacetimes Conformal to Einstein Spaces
G. Bergqvist, I. Eriksson
In this paper we characterize the source-free Einstein-Maxwell spacetimes which have a trace-free Chevreton tensor. We show that this is equivalent to the Chevreton tensor being of…
Conserved Matter Superenergy Currents for Hypersurface Orthogonal Killing Vectors
Ingemar Eriksson
We show that for hypersurface orthogonal Killing vectors, the corresponding Chevreton superenergy currents will be conserved and proportional to the Killing vectors. This holds for…
New electromagnetic conservation laws
G. Bergqvist, I. Eriksson, J. M. M. Senovilla
The Chevreton superenergy tensor was introduced in 1964 as a counterpart, for electromagnetic fields, of the well-known Bel-Robinson tensor of the gravitational field. We here prov…
