Description

Tensorial 3.0: A General Tensor Calculus Package.

The package should be useful both as an introduction to tensor calculations and for advanced calculations. Some of its features are:
  1. There is complete freedom in the choice of symbols for tensor labels and indices.
  2. Base indices may be any set of integers or symbols. Thus you could use {0,1,2,3} for relativity problems, or {t,x,y,z}, or {&rho,&theta,&phi} for spherical coordinates.
  3. Flavored indices (colored or annotated symbols) to represent different coordinate systems.
  4. Tensor shortcuts for easy entry of tensors.
  5. Easy methods to store and substitute tensor values.
  6. Partial, covariant, total, absolute and Lie derivative routines for any dimension and any order.
  7. Complete documentation, with a Help page and numerous examples for each command. In addition there are tutorial and extended example notebooks.
  8. There is an additional package "TMecanica", showing an advanced application of Tensorial for Hamiltonian dynamics.
Tensorial 3.0 can be found at http://home.earthlink.net/~djmp/Mathematica.html

The notebooks here are an older version, Tensorial 1.3
