#5705: [with patch, positive review] homogenize() does not respect the rule that
parents are unique
---------------------------------+------------------------------------------
Reporter: malb | Owner: malb
Type: defect | Status: new
Priority: major | Milestone: sage-3.4.1
Component: commutative algebra | Keywords:
---------------------------------+------------------------------------------
Comment(by SimonKing):
Indeed, without the patch, we have
{{{
sage: R=PolynomialRing(QQ,'x',5)
sage: p=R.random_element()
sage: q1=p.homogenize()
sage: q2=p.homogenize()
sage: q1.parent() is q2.parent()
False
}}}
With the patch, that cleanly applies, we have
{{{
sage: R=PolynomialRing(QQ,'x',5)
sage: p=R.random_element()
sage: q1=p.homogenize()
sage: q2=p.homogenize()
sage: q1.parent() is q2.parent()
True
}}}
So, I give it a positive review.
