Nature of problem:
Arbitrary calculations in general relativity using Ricci calculus according to the restrictions below.
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.
Computer algebra program written to aid the manipulation of abstract indices in general relativity.
This depends on both the problem to be solved and the speed, memory of the machine in question.
