Abstract
The MathTensor software enables to calculate the curvature invariants
of
dierentiable manifolds in the case when the dimension of manifold
under
consideration is a concrete number. Proving the existence of geometric
ob-
jects it is important to have examples for all dimensions n; greater
or equal
to some n 0 ; i.e. when the dimension is just a symbol.
The aim of the paper is to show how, using MathTensor and Mathematica
commands, one can define the covariant and contravariant components
of the
metric tensor. Then we will show how to define different curvature
tensors
and how to execute the calculation of their components.
