Description (last modified by )
I made a clean hg bundle against sage-4.1.1 that includes patches 1-16 along with the patches from 6745 and 6751:
http://sage.math.washington.edu/home/wstein/patches/heegner-1-to-16.hg
NOTE: If you apply patches, the code after part 7 depends on #6745, #6751, so make sure you apply those patches!
PLAN:
- Refactor ell_rational_field, so the Heegner points code (nearly 1000 lines!) is in a new file heegner.py.
- Extend the heegner point code to compute y_lambda for lambda > 1.
- Implement first ever algorithm for provable verification of Kolyvagin's conjecture for specific rank 2 curves.
I'm doing 1 and 2 together, since 2 is a fairly small change, but to do it right and make it at all fast requires restructuring the code a lot, otherwise one ends up fighting a lot with badly structured code instead of focusing on optimizing algorithms.
Also, this refactoring is a long time coming!

This calculation uses massive RAM:
sage: E = EllipticCurve([877,0]) sage: P = E.heegner_point(-7) sage: P Heegner point of discriminant -7 on curve of conductor 49224256 sage: N(P) [approx 5GB RAM (?) -- didn't wait for it to crash my laptop]
This should get dealt with. No clue what causes this.

This is a clean bundle against sage-4.2.alpha0:

Review: I am immensely impressed by the huge amount of work which has gone into this ten thousand-line patch! It goes far beyond the refactoring of the title.
I read through the patch itself, and liked what I saw. (There are a few minor typos in the docstrings, which I did not note as I went through -- sorry). Some docstrings which did not format properly: numerical_approx, rational_kolyvagin_divisor, KolyvaginPoint?.
There are a lot if interesting mathematical and algorithmic issues which are highlighted very well in comments and TODO blocks, which is good.
Testing all files in the elliptic_curves directory I found these problems.

In heegner.py it's mainly a mixture of numerical noise and hash differences (this is on a 32-bit machine), but not all. Details:

So the conclusion is, regretfully, "needs work", though the work that needs doing is trivial compared with what has been done already (which is probably worth a PhD thesis for someone!).

I posted a new patch fixing all the issues above, except possibly the "very weird" ell_rational_field issue. I couldn't replicate that on any test machine yet.
I also didn't carefully reformat the docstrings. Which ones aren't formatted correctly? I thought I had got them right.

was> That's in a doctest for something probably unrelated, so can be safely
ignored for refereeing.
Ignoring that, there was just one small thing (testing on 64-bit), namely
File "/home/jec/sage-4.3.1.alpha1/devel/sage-tests/sage/schemes/elliptic_curves/heegner.py", line 277: sage: hash((-7,5)) Expected: -3713088127102618519 1817441385 Got: -3713088127102618519
which is just because someone forgot to add the tag # 32-bit. I added that by editing the patch, and the corrected version is now attached here.
So: positive review on 64-bit. I'll test on 32-bit when I get home (leaving now, hope I do not get buried in the snow...)
comment:20 Changed 10 years ago by
- Status changed from needs_review to positive_review
Positive review after testing on 32-bit, and also fixing lots of documentation glitches (in the reviewer's patch). These were mainly found by actually running "sage -docbuild all html" and reading the error messages (hint hint). Most common error was double :: where they shouldn't be.
Great work!
