Dear Carl,
I like your code; it is elegant and realy quick
but it seems that finishing your code
with Paul Zimmermann's approach
I2 = singular(I).groebner()
#print I.reduce(n12);
print singular.reduce((n12), I2)
(althout less elegant)
is a little bit faster

Hi everybody,
in a nutshell I want to compute something like this MAGMA session in Sage:
%magma
Pa,b,c,d := PolynomialRing(GF(127),4);
I := idealP|c^3-b*d^2,b*c-a*d,b^3-a^2*c,a*c^2-b^2*d;
St := HilbertSeries(I);
S;
Lu := LaurentSeriesRing(IntegerRing());
L ! S;
The first part is quite easy as

Hi,
Using sage-2.9.3, on Debian Etch on a core duo machine.
According to the sage tutorial p.67 section 5.3 Standalone Python/Sage
Scripts, i tried to run such a script called BMV.sage:
#!/usr/bin/env sage -python
import sys
$ ./BMV.sage
/usr/bin/env: sage -python: file or directory not found
it worked, thank you :)

It might be a lot easier to help if you gave the rational function.
Depending on how complicated the denominator is, you basically just have to
compute the Taylor series of the rational function, by differentiation and
evaluation (using Taylor's formula), i.e., kind of like this is doing,

Kevin,
I have been taking the same plunge (and prbably for the same reason).
It's not clear whether knowing C++ well was a help or a hindrance. I
have just read the book Learning Python by Lutz, published by
O'Reilly, and

Georg,
1. Is this a clean, from-source build of sage-2.9.3?
2. What is the output of /usr/bin/env for you? Mine (Intel OS X
10.5.1) doesn't mention sage at all, although mysteriously things are
working for me.

For me, I get

Yes, i tried it out on two different systems now, Athlon XP, and Core Duo,

Hi:
I have an old 64 bit machine with 64bit ubuntu fiesty fawn loaded on it.
I just noticed a problem with plot3d on it (plot3d runs fine on my
intel macbook):
In sage 2.9.3:
sage: x = var(x)
sage: y = var(y)
sage: p = plot3d(x^2-y^2,(-1,1),(-1,1))
17 matches
