title = "Review of some classical gravitational superenergy tensors using computational techniques",
abstract = "We use computational algorithms recently developed by ourselves to study completely four index divergence-free quadratic in Riemann tensor polynomials in GR. Some results are new and others reproduce and/or correct known ones. The algorithms are part of a Mathematica package called Tools of Tensor Calculus (TTC).",
keywords = "Simplification",
author = "A. Balfagon and X. Jaen",
note = "We want to kindly thank J.M.M. Senovilla to direct our work on superenergy tensors. X.J. would like to thank the Comisi{\'o}n Asesora de Investigaci{\'o}n Cient{\'i}fica y T{\'e}cnica for partial financial support, under Contract No.PB96-0384.
