SUSSMAN, R.A.. Definición y cálculo de tensores mediante el paquete GRTensor. Rev. mex. fis. [online]. 2007, vol.53, suppl.4, pp.159-170. ISSN 0035-001X.

The package GRTensor allows one to define, calculate and manipulate tensors of arbitrary range and dimension from the components of a metric, either in a coordinate basis or tetrad. By considering simple and instructive examples we implement basic applications of this package to define and compute tensorial objects of common usage in General Relativity.

Palabras llave : Computer algebra; general relativity; tensors.
