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.

Keywords : Computer algebra; general relativity; tensors.
