Positivity and conservation of superenergy tensors
Jose M. Pozo, Josep M. Parra
Two essential properties of energy-momentum tensors T_{μν} are their positivity and conservation. This is mathematically formalized by, respectively, an energy condition, as the do…

Clifford Algebra Approach to Superenergy Tensors
Jose M. Pozo, Josep M. Parra
Senovilla has recently defined an algebraic construction of a superenergy tensor T{A} from any arbitrary tensor A, by structuring it as an r-fold form. This superenergy tensor sati…
