In each case below "I" and "J" are defined by different choices of generators and are recognized as the same ideal. In case 1 the quotients are considered equal and in case 2 they are considered unequal.
(I checked this with the latest version) Case 1: ---------- sage: R.<x> = PolynomialRing(QQ) sage: I = R.ideal([x + x^2, x]) sage: J = R.ideal([2*x + 2*x^2, x]) sage: S = R.quotient_ring(I) sage: U = R.quotient_ring(J) sage: I==J True sage: S==U True Case 2: ---------- sage: R.<x> = PolynomialRing(QQ) sage: I = R.ideal([x + x^2]) sage: J = R.ideal([2*x + 2*x^2]) sage: S = R.quotient_ring(I) sage: U = R.quotient_ring(J) sage: I==J True sage: S==U False *** Cheers!
