PS:
Singular offers to use an "extra weight vector" (see
http://www.singular.uni-kl.de/Manual/latest/sing_748.htm#SEC800).
Sadly, if one uses it, then one automatically gets a degree order. So,
it would not solve our problem.
Cheers,
Simon

I said two things.
One statement was: The matrix term ordering should not interfere with

I've opened http://trac.sagemath.org/sage_trac/ticket/11837 for adding
Newton basin fractals to Sage. It turns out that even I could modify
complex_plot to create these, after a few false steps. Sage-edu fans
will perhaps be interested in this - if you've ever played with

Hi Martin,
by the way, I'm also giving a talk at this meeting, although not
Sage-related. Anyhow, hopefully I'll have time to drop by your talk...

Simon,
I have seen graded rings before, for example when defining homogeneous
rings one has standard and non-standard gradings. But the grading
wasn't determined by a term ordering in those cases, and I have seen a
distinction between the two: a recent paper on Computing Inhomogeneous

Is there any way in sage, or rather python, to define a function which
takes as its input n variables, rather than assigning a fixed
number?
I've just written a piece of code for the Quadratic Forms module,
which takes as input a Quadratic Lattice, Q, and three vectors, so
(Q,v_1,v_2,v_3), and it
