Energy and electromagnetism of a differential form
J. Navarro, J. B. Sancho
Let X be a smooth manifold of dimension 1+n endowed with a lorentzian metric g, and let T be the electromagnetic energy tensor associated to a 2-form F. In this paper we characteri…

A characterization of the electromagnetic stress-energy tensor
J. Navarro, J. B. Sancho
In a previous paper, we pointed out how a dimensional analysis of the stress-energy tensor of the gravitational field allows to derive the field equation of General Relativity. In…

On the naturalness of Einstein's equation
Jose Navarro, Juan B. Sancho
We compute all 2-covariant tensors naturally constructed from a semiriemannian metric which are divergence-free and have weight greater than -2. As a consequence, it follows a char…
