Description (last modified by )
This patch restructures the implementation of symmetric functions in sage
The new implementation makes use of multiple realizations and the category framework. The new access to symmetric functions is via
sage: Sym = SymmetricFunctions(QQ)
Further new features that are implemented:
- The ring of symmetric functions is now endowed with a Hopf algebra structure. The coproduct and antipode are implemented (which were missing before).
- A tutorial on how to use symmetric functions in sage is included at the
beginning of sf.py which is also accessible via
sage: SymmetricFunctions??
- Symmetric functions should now work a lot better with respect to
specializing parameters like
q
andt
for Hall-Littlewood, Jack and Macdonald symmetric functions. Certain functionalities before this change were broken or not possible.
- Documentation was added to LLT polynomials (which had very sparse documentation previously).
- The
k
-bounded subspace of the ring of symmetric function was implemented. Thek
-Schur functions now live in thek
-bounded subspace rather than in the ring of symmetric functions as before.
This patch gained tremendously by the tutorial on symmetric functions written
by Jason Bandlow and Nicolas Thiery, a draft on the k
-bounded subspace by
Jason Bandlow, and code multiple realizations written by Franco Saliola.

Hi Mike,
I completed the doctests for sfa.py and also rebased everything on top of 13109. Please put your changes to
- hall_littlewood.py
- jack.py
- llt.py
- macdonald.py
on top of the current patch trac_5457-symmetric_functions-mz.patch. Unfortunately we need to abandon the sage-combinat queue for the moment since it would be very cumbersome to keep it backward compatible with 13109. I will send you a separate e-mail on how to proceed.
Cheers,
Anne

Ok, patch is ready for review! It should apply and run cleanly on sage.5.2.rc0!

Hi Dan!
Thank you very much for your comments on the failing doctests in
- devel/sage/sage/algebras/nil_coxeter_algebra.py
- devel/sage/sage/categories/realizations.py
They are fixed in the updated version of the patch. I do not get failures for
- devel/sage/sage/sandpiles/sandpile.py
on my machine.
lolita-4:sandpiles anne$ sage -t sandpile.py sage -t "devel/sage-sf/sage/sandpiles/sandpile.py"
[19.0 s]
All tests passed! Total time for all tests: 19.0 seconds

I also get a doctest failure in sandpile.py with unpatched sage-5.2.rc0 so this failure is not caused by the patch.

Applies cleanly to sage-5.2 and passes all tests.

The attached review patch trac_5457-review-as.patch incorporates most of the comments that Dan Bump raised in e-mail conversations.

This patch is a huge step forward for symmetric functions.
In addition to normal testing I spent quite a bit of time and privately sent comments (mainly on documentation) that have been taken into account in trac_5457-review-as.patch. I'm changing the status to positive review.

Dear Dan, Thank you so much for your thorough and quick review of this huge patch! Mike and I just finished the review patch. Tests pass on both of our machines.

I have reviewed the latest version of the patch and it still has positive review.
comment:28 in reply to: ↑ 27 Changed 9 years ago by
Since http://trac.sagemath.org/sage_trac/ticket/12969 just got merged into sage-5.3.beta0, please also apply the attachment trac12969_rel_5457.patch on the ticket 12969 to this patch. Otherwise there will be doctest failures.
Thanks,
Anne

Hi Mike,
I finished the doctests for the following files:
In particular, at the beginning of sf.py I incorporated the tutorial that Jason and Nicolas wrote (which was further down the queue) and updated it. I marked them there as coauthors in that file.
This leaves the doctests for
which I suppose you will do in the next couple of days? In particular, in the sfa.py the deprecation warnings need to be activated which I have not yet done.
Best,
Anne
