Thank you,
and i already tried this. In this case it obiously does work but in case i
have denominators, can u explain me how to solve it?
for example: K(s/(s+t),s^2*t^2) then i have to calculate the elimination
ideal of ((a0-s,a1-s^2t^2):(s+t)^\inf) where (I:J^\inf) is the saturation
of I wit
Have you tried using elimination ideals?
K=QQ['s,t,a0,a1,a2']
K.inject_variables()
I = Ideal( a0-s^2, a1-t^2, a2 - (s^2+t^2))
I.elimination_ideal([s,t])
Ideal (a0 + a1 - a2) of Multivariate Polynomial Ring in s, t, a0, a1, a2
over Rational Field
So a2 = a0 + a1
The elimination ideal tells you wh
