Hi,
I think this email properly belongs to sage-support.

Hi,
I think this email properly belongs to sage-support.

Hi all,
I was going through the SAGE manual and it seems that there is no way
to use function fields in SAGE.
More concretely, one can define FiniteField(3)., but cannot define
extensions of it.
Is there somebody who knows if this is in the making (I saw that there
is a SAGE Function Field days
Hello everyone, I'm new to sage ;-)
we have two disjoint sets S1,S2 of size 168 in a field of order
3^6=729. We are looking for a univariate polynomial over this field
mapping S1 onto S2. Of course Lagrange interpolation gives a
polynomial with degree 167. But there are many choices for such
polyn
Hi Rajeev,
thanks, that's very useful,

I don't think so, but it might make a really great senior project to
implement some basic stuff, as there are now several accessible
introductions at the late-undergrad/early-grad level. Also, do you
know if any of the current

In which case you would want to do for example:

Hello,
I have an interesting problem and I hope it is possible to solve it using

I have a scanned digitized graph of a magnetic hysteresis loop.
That is, I have a list of points [(H0,B0),(H1,B1)(Hn,Bn)]
however, the points are not ordered in any meaningful way.
