Hi -
Has anybody worked on porting Singular 4.1.1 to Sage? (4.1.1 was released
in February; 4.1.1p2 was released on Monday)
I'm having problems loading "brillnoether.lib" into the Singular 4.1.0p3
that's current with Sage develop (just try to load it if you want to see it
fail), so I thought
Hi -
I'd like some guidance on how to move some of my tickets forward, #25351,
for example. Once #25351 is closed, then we can move on to #25390, which
depends on #25351 and will give us multivariate polynomial factorization
over QQbar.
Patchbot shows two test failures on #25351 involving mag
Hi -
I'm trying to get the DifferentialAlgebra package in issue 13268 running
(it has a github branch that was imported from trac).
Last time I had it running was 9.0 (I think), and now I'm trying to build
it on 9.8.
It seems to build fine, but can't access functions in the shared library

Hi -
I don't think giac can handle more than 15 variables in a Gröbner basis
calculation.
This limitation isn't really documented anywhere, but if you look in giac's
src/cocoa.cc around lines 490-500, function swap_indices and think about it
a few minutes, you'll see that it can't handle more

I see, now. Thank you.

This is what I figured out to adjust Singular's printlevel:
from sage.libs.singular import function_factory
execute = function_factory.ff.execute
execute('printlevel=-1')
Now that previous example runs without all the clutter:
sage: R. = GF(3)[]
: S = R.quo(ideal(y^4 + y - x^5))
: from
Expanding on my previous answer, I found a way to save printlevel and
restore it when I'm done. The key idea is try to get a handle to a
function that may not exist, then create it if it doesn't:
from sage.libs.singular.function import singular_function, lib
lib('normal.lib')
normal = singular_

I'd suggest setting AA.options.display_format = 'radical' to eliminate the
"numerical noise".

I know the Risch algorithm fairly well.
I made two screencast videos describing how to use Axiom or Sage to
simplify one of the integrals used in the Facebook paper.
Quick summary - Axiom works quite well. Sage can't do it in one step, but
the new function field features in Sage 9 allow the i
