Program title: RICCIR
Catalogue identifier: ADCV_v1_0
Distribution format: tar.gz
Journal reference: Comput. Phys. Commun. 93(1996)265
Programming language: RLisp, Reduce.
Operating system: UNIX SOLARIS 2.4.
RAM: 340K words
Keywords: Computer algebra, General relativity, Ricci calculus, Tensor algebra.
Classification: 5.

Nature of problem:
Arbitrary calculations in general relativity using Ricci calculus according to the restrictions below.

Solution method:
Implementation of Ricci calculus in computer algebra.

Calculations in concrete components of tensorial expressions are not possible. The built-in relations are valid in the case of Riemann manifolds without torsion.

Unusual features:
Computer algebra program written to aid the manipulation of abstract indices in general relativity.

Running time:
This depends on both the problem to be solved and the speed, memory of the machine in question.
