In case you are interested in using FriCAS to extend Sage, I'd be glad to actively work on that (and thus, as a side effect, join sage). I don't know what exactly you have in mind, so what follows is a rather random list of related topics. Already built into FriCAS are several domains for differential polynomials etc. Feel free to ask for details. FriCAS has a rather elaborate implementation of the Risch algorithm, and is thus quite good at solving linear differential equations. Waldek told me once he is working on improving support for algebraic differential equations. I have a private package for computing with algebraic equations as well as linear differential and algebraic differential equations. Many interesting operations like addition, product, inverse, substitution, etc. work, most embarassing omission is a zero test. One other thing built into FriCAS which I'm quite proud of is the guessing package, see http://arxiv.org/abs/math/0702086 . This might also be helpful for some applications in the area. I'd be too glad, Martin -- To post to this group, send an email to sage-devel@googlegroups.com To unsubscribe from this group, send an email to sage-devel+unsubscr...@googlegroups.com For more options, visit this group at http://groups.google.com/group/sage-devel URL: http://www.sagemath.org
