Review of some classical gravitational superenergy tensors using computational techniques

General Relativity and Quantum Cosmology 2009-10-31 v1

Abstract

We use computational algorithms recently developed by us to study completely four index divergence free quadratic in Riemann tensor polynomials in GR. Some results are new and some other reproduce and/or correct known ones. The algorithms are part of a Mathematica package called Tools of Tensor Calculus (TTC)[web address: http://baldufa.upc.es/ttc]
