[sage-devel] Solving a gcd equation for polynomials

2011-05-24 Thread Rob Beezer
I'm wondering if Sage has the following function for polynomials over a field. Mostly, I don't know if it is a common thing to expect, and if so, I have no idea what it would be called. So a pointer would be of real help, if it exists. The paper I am cribbing from is about matrices over ZZ, but

If you are using Volker new ATLAS spkg can you tell me what you get from this doctest: sage -t -force_lib "devel/sage/sage/modular/modsym/space.py" We found in sage-on-gentoo that this test fails with some ATLAS-3.9.xx. Francois -- To post to this group, send an email to sage-devel@googlegroup

[sage-devel] Conversion between polynomial rings with different termorder

I am not sure if this is a bug or an unexpected bud valid behavior, since we are dealing with conversions instead of coercions. {{{ sage: K1=PolynomialRing(QQ, 't',10, order=TermOrder('degrevlex', 4) + TermOrder('degrevlex', 6) ) sage: K2=PolynomialRing(ZZ, 't',10) sage: [K2(f) for f in K1.gens()]

This is also a great example of the difference between '=' and '=='. If the statement a = b, where to precede everything, then Sage would know that a - b = 0, and would convert the statement 'a==b' to 'b==b', which would frustrate the proof. Jonathan On May 23, 1:44 am, David Kirkby wrote: > On
