The following code does not run in a Jupyter notebook inside cocalc
R. = PolynomialRing(QQ)
f = x^3+6*x^2+12*x+8;
g = x^2+x-2;
I = R.ideal([f]);
J = R.ideal([g]);
I.intersection(J)
This produces an error that ends with the line:
AttributeError: 'Ideal_1poly_field' object has no attribute
Hi Luis,
It's actually not a bug, but a missing feature. The problem is that in
the first case R is a *univariate* polynomial ring, and in the second case
it is a multivariate polynomial ring and different functionality is
available in each case. Read the docs for PolynomialRing (via
