I assume you want to do 2 things: 1. translate their PDE solver (numerical or symbolic?), 2. translate the DG computation package. For 2, I'd contact the guy who presented the work at the conference and tell him what you'd like to do. Better yet, you could ask him for help. For 1, I imagine this would be quite difficult and don't see that "copying" would be an issue. Maple is Pascal-like, as is GAP, and is much different than Python. You'd probably end up rewriting an enormous amount of code, finding your own improvements along the way. In any case, I imagine the PDE solver came from someone's work and it would be nice if you could track him/her down and tell him/her your plans as with the DG package. You could post to sci.math.symbolic or maybe email some Maple users group.
BTW, a differential forms package has just been (or is being, as we speak) added to the "bleeding edge" version of Maxima. I get the impression that the code is written by a Japanese grad student with not great English language skills, so expect very little English documentation. However, some other people on the maxima users list are saying very nice things about it. This may or may not help with your other project, but just thought I'd mention it. +++++++++++++++++++++++++++++++++++++++++++++++ On 10/30/06, Joshua Kantor <[EMAIL PROTECTED]> wrote: > > I was at a conference this weekend where someone presented a maple > package they had been writing for doing certain differential geometry > computations.
