Hi,
this might be a design decision, so I haven't filed a bug report for it yet.
However, it seems that coefficient is returning the wrong type when it's
called on multinomials. Here is an example code:
sage: K.=QQ[]
sage: f = x^3+y^3+z^3
sage: f.coefficient([3,0,0]).parent()
Multivariate Polynom
Hi all,
I wanted to play around with parallel age code a bit, and so I tried to
install mpi4py package in sage 3.4. However, during the build process, swig
complains that -O option is unrecognized. Has anybody else used this package
recently? (The swig installed is version 1.3.21)

Is there a particular reason why the log_repr in finite fields returns a
string instead of an integer?
Actually, more important than that, the following fails:
F=GF(5)
r=F.multiplicative_generator()
r.log_repr() <--- comes back with an error
log(r,r) < also comes back with an error.
This is n

Hmm, I must say from using maple on expr
It would be nice if one had a way of checking the code of a procedure that
is called inside of another function. Specifically, when you type
M.myfunc??, sage prints out the source code, and in many cases, this code is
very generic, that calls another function, possibly after checking some
boundary

Hi,
compiling fails for me on linbox. Apparently it can't find blas libraries.
My computer is an hp laptop, with amd 64x2 processor, running gentoo. I have
acml installed on my computer, although looking at install.log it seems like
sage is compiling atlas libraries as well, so I'm not sure if tha

Hi,
there seems to be some exciting progress in making packages for sage.
However, I'm curious if there is a plan for allowing normal users have their
own sage libraries that they can edit. That is, if a normal user runs "sage
-clone" on a sage that is globally installed, a copy of the cloned dire

Hi,
I'm actually really excited that you've got as far. Do you have an ebuild

Another *possible* way of sage behaving is
sage: P.=ZZ[]
sage: f=x*y^2+x*y+y+x+1
sage: f.coefficient(y^2)
0
sage: f.coefficient(y^1)
1
sage: f.coefficient(y^0)
1
Now, I'm not sure if this is better or not, but I thought maybe I should
point it out. The biggest problem with this is that if you do
I think what you're saying makes sense. Maybe introduce a method
fractionalideal, specific to number fields?

Hmm, there seems to be many assumptions that I would like it be clarified.
Specifically where do all these objects live in.
For example, sin is a function from K->K.
same as cos. If that's the case, then sin+cos makes perfect sense.
Can we make the same assumtion for x? Is it safe to assume x is a
I'm sure the overhead is tiny, but you are also calculating f' in each
iteration.

vectorspaces are Abelian groups under addition.

Hi,
I am trying to implement scalar division in sage, and I'm starting to get a
bit confused about the class hierarchy. I believe that a while ago there was
some discussion about the class hierarchy, but I have no idea what the
results were, and I figured I will just ask my questions here.
First,
Sure. I'm essentially following the same technique used in Seng-Kiat Chua
and San Ling's article "On the Rational Cuspidal Subgroup and the Rational
Torsion Points of J_0(pq)", and my thesis (arXiv:0707.0437).
Let L be the space of functions on the upper half plane generated
(multiplicatively) by e
Hi,
I was writing a function to calculate the structure of cuspidal subgroup of
J_0(N) without using modular symbols. I came across the following puzzling
bug. Here is a procedure which produces a matrix
def generate_cond5(l,r):
M=Matrix(QQ,l,r)
for j in range(l):

I think there is a bug in hecke_matrix code right now.
I get the following results, running sage on sage.math computer:
