Manuscript Title: Ricci calculus package in REDUCE. | ||

Authors: J. Kadlecsik | ||

Program title: RICCIR | ||

Catalogue identifier: ADCV_v1_0Distribution 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. | ||

Restrictions: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. |
