Comment:
I'm going to set the patch to "needs review", firstly since as burcin
pointed out in a private email, the licensing situation of the mathematica
package is somewhat unclear, and secondly the implementation of the
differential forms class is sufficiently simple so that the issue won't be
with the algorithms that I used but rather whether this is good sage
programming.
Some things to keep in mind: right now, the way to create a differential
form is as follows: first you create a !``CoordinatePatch!`` on which
forms can be defined, then you create a !``DifferentialForms!`` parent and
then you can create forms. Explicitly, this looks like
{{{
sage: x, y, z = var('x, y, z')[[BR]] sage: U =
!CoordinatePatch((x, y, z))[[BR]] sage: F =
!DifferentialForms(U)[[BR]] sage: form = !DifferentialForm(F, 0,
sin(x*y)); form[[BR]] sin(x*y)
}}}
Let me know if this construction is confusing or can be simplified in any
way.
