Exterior Differential Calculus

and

Symbolic Matrix Algebra @ Mathematica

 

This package enables Mathematica to carry out calculations with differential forms. It defines the two basic operations - Exterior Product (Wedge) and Exterior Derivative (d)  - in such a way that:

  (1)  they can act on any valid Mathematica expression
  (2)  they allow the use of any symbols to denote differential forms
  (3)  input - output notation is as close as possible to standard usage
