Gravitation
http://www.maplesoft.com/applications/view.aspx?SID=4891&ref=Feed
An object-oriented package for gravitational tensor calculation, comprising calculation of;
- the Levi-Civita connection, the Riemann tensor, the Ricci tensor, the Ricci scalar, the Einstein tensor, the Weyl tensor, and the Kretschmann scalar
- the spin connection, and the spin curvature tensor
The package treats all the following three cases;
- the purely metric case
- the purely tetrad case
- the mixed case, where both metric and tetrad are present (may, or may not, be independent)
The package is able to treat as independent variables the metric, the Levi-Civita connection, the tetrad, and the spin connection<img src="/view.aspx?si=4891//applications/images/app_image_blank_lg.jpg" alt="Gravitation" align="left"/>An object-oriented package for gravitational tensor calculation, comprising calculation of;

http://www.maplesoft.com/applications/view.aspx?SID=1734&ref=Feed
A package for computation with differential forms, using neither neutral- nor rebound operators
The package treats both p-forms and p-vectors (p-vector-units being the duals to p-form-units), and their mutual interaction through interior multiplication
Powerful commands like multiplication, duality, and differentiation are included in the package<img src="/view.aspx?si=1734//applications/images/app_image_blank_lg.jpg" alt="A Maple Package for Computation with Differential Forms" align="left"/>A package for computation with differential forms, using neither neutral- nor rebound operators
