Apologies if this is the wrong place to ask this question. Does SAGE incorporate support for differential algebra? That is can it handle differential rings/ideals and does it have an implementation of the Rosenfeld-Groebner and Ritt algorithms? Thanks, Daniel

See http://en.wikipedia.org/wiki/Differential_algebra - related to D- modules, but not the same. Kaplansky has a book about this I've always meant to read... Maple definitely supports this; it was unclear whether Mma does, though apparently not directly. I could not find any reference to this

Thank you very much for your prompt reply!! I was able to compile sage-3.4 on the OLPC XO. It took 3 days !! More than half of the time was spent in linbox, in particular compiling linbox-sage.C. Since the XO tripped on the same ATLAS bug as Solaris, I removed ATLAS from sage-3,4 - slight

I had not heard of SnapPy before, so I can't help much, but did you follow the sage installation directions from their documentation? http://www.math.uic.edu/~t3m/SnapPy/doc/installing.html#sage The fact that they have that much is an encouraging sign, it should be possible to do this.

Here's how to install SnapPy on the VMWare version of SAGE; you have to do a little hack to account for the fact that certain header files are missing. wget -nd http://www.math.uic.edu/~t3m/SnapPy/SnapPy.tar.gz tar xfz SnapPy.tar.gz; cd SnapPy sudo sage -python -m easy_install -U cython sudo
