I'm doing my masters at the moment and I plan on running sage quite a bit

Hello!
I am trying to use unicode characters in axes labels and it fails with

P.show(axes=False,frame=True,axes_labels=('текс','x'))

If I have a boolean expression of a certain number of variables, how
do I define a polynomial ring with them.. For example, let
(x0,x1,x2,x3,x4,x5,x6,x7) be a set of variables, and I have an
expression S = x0 + x1*x3 + x7
I need to define the polynomial ring
R=BooleanPolynomialRing(100,['x'+str(i) for i in [1..100]])
R.inject_variables()# if you don't really need the identifiers in
Python's namespace, better skip this

Hi
sagenb doesn't seem to be working. A student of mine is about to
defenestrate herself (her words) because it's not working.
If this is expected downtime; my apologies -- she wasn't supposed to
be using sagenb in the first place, but that's life. :-)

test.sagenb.org seems to be up, so if she has a saved local copy of a

Hi, all,
I'm new here and new-ish to sage and I was hoping you could help me
with a rather complicated problem. My professor gave me this
inequality:
0 (2*n*(i+j+k))/(-k*n+j*(n-s)+i*s) 1
and he wants me to see if I can find solutions within the following
constraints: 0 s n, i,j,k integers,

I don't think maxima does polyhedral computations in its assume facility,
so you probably get the wrong answer.
We do, however, have quite a lot of tools for polyhedral computations:
sage: P = Polyhedron(ieqs=[(1,2), (10,-7)])
sage: P
A 1-dimensional polyhedron in QQ^1 defined as the convex

For the curious: http://en.wikipedia.org/wiki/Defenestration
Defenestration is the act of throwing someone or something out of a
window.[1] The term defenestration was coined around the time of an
incident in Prague

That would explain why it wasn't working. I've never done polyhedral
computations before, but I will look at your example and the reference
manual and see what I can do!
Thank you!

Here is a first implementation of the cup product. I hope (of course) that
the code is correct, but it is certainly not very idomatic. Any suggestions
for improvement are welcome!

I am trying to set up sage using vitualbox. What base memory should I
set in virtualbox for the sage ? While setting up, I assigned 1024 MB
base memory. Later the Virtualbox keeps reminding me that base memory
is more than 50 % of total memory (1.74 GB) and there might be
problems.
