#10902: missing terms in factorization of multivariate polynomials
---------------------------------------+------------------------------------
Reporter: zimmerma | Owner: malb
Type: defect | Status: needs_work
Priority: critical | Milestone: sage-4.7.2
Component: commutative algebra | Keywords: sd34
Work_issues: Proof=... still present | Upstream: N/A
Reviewer: | Author: Martin Albrecht, Paul

Merged: | Dependencies: #10903
---------------------------------------+------------------------------------
Changes (by zimmerma):
* work_issues: spkg fails to build => Proof=... still present
Comment:
I finally managed to apply the 4 patches, I ran {{{sage -b}}}, then
installed the spkg, then ran
{{{sage -b}}} again.
However {{{Proof=...}}} seems to be still present somewhere:
{{{
sage: R.<x,y> = GF(2)[]
sage: p=x^8 + y^8; q=x^2*y^4 + x; f=p*q
sage: f.factor(proof=False)
x * (x + y)^8 * (x*y^4 + 1)
sage: f.factor()
...
NotImplementedError: proof = True factorization not implemented. Call
factor with proof=False.
}}}
