My question is certainly a simple one, however I did not guessed the point.
In the Help Manual "D.7.5.2 Factor" you give the following Example:
ring R = (0,a), x, lp;
minpoly = a2+1;
poly f = x4 - 1;
list fl = Factor(f);
- which is just (x-1)*(x+1)*(x-a)*(x+a) where the factors are modified by some invertible elements of Q(a)[x] having their product = 1. (some complex rationals actually)
My question is: what is the property that single out the Singular answer in the above example, out of the many others, which all just differ by invertible factors?
Thanks for the answer,
