A variation on your first try is:
sage: ((a*b - (1/2)*a*(b - c))/a).simplify_radical()
(c + b)/2
which works fine. Maybe it's a bug in maxima. I don't see why you
would need simplify_radical() at all here, since your expression
contains no radicals.

When I was trying to perform the same calculations in Sage I
(..., {eqs}) command, which computes the normal form of a
polynomial with respect to a set of polynomial equations. This is quite useful
for the user who is not aware of Gröbner bases (or the aware-user who prefers
a simple command). Does a similar command exist in SAGE?

I've made the bug you point out above trac #1773:

Could it be related to the spaces around '='?

superficially to be the elementary solution to the question of
odd'th roots of negative reals just leads to horrendous internal
problems if followed through. Maths is not always simple.

need to
compute and display Taylor polynomials of matrices. Hopefully there
is some way I can keep a polynomial in x-1 from getting simplified
automatically when it's an element of a matrix.

may this method could be useful for others, too

Is it possible to work in a polynomial ring over a fraction field, and
if yes, how?

Dear Benedikt,
There is code to compute the Weil pairing using a gp script (written
by me) which sage includes, but at present there is no wrapper for it
to be used in Sage. Either that could be done, or someone could
rewrite that gp script in Sage.

For the record, I am able to successfully (if slowly) build Sage on my
aging laptop with 512MB of RAM. So it seems that the critical value
is somewhere between 256 and 512.
On the other hand I'm not sure that I have actually done this since
about 2.9 and it gets bigger (and better!) with each

If you look at Franco's Sage talk (poseted here recently) he includes
a screenful of poset examples (on page 50, near the end of the
presentation) -- which in fact makes it look as if it's in Sage
already. So unless that page of the talk is wishful thinking, he must
have made some real progress
PS Sorry that should have read posted and not poseted , ha ha.
