Description (last modified by )
This patch implements a new class of weak k-tableaux. It also removes white spaces from core.py.
The methods on k-charge were contributed by Nate Gallup and Avi Dalal during Sage Days 49 in Orsay.

Hey Anne and Mike,
Thank you both for your work on this. However there are a few things I've noticed while glancing over the patch:
- The inner bullet list on the
INPUT:
block forWeakTableau
has one too many spaces, so it is overly indented. It needs to line up as follows:- item 1 - inner item a - inner item b - item 2
k_charge_I()
andk_charge_J()
have the same docstring. In fact, it might be worthwhile to actually describe the algorithm.- I think it is worthwhile to have one abstract base class for all
WeakTableau
elements which has it's abstract methods defined. For example, you can also consolidate all of the more detailed explanations of the methods in there and link to them in their concrete classes. In particular, it because an easier/more straightforward to check to see if it's aWeakTableau
and allow you an easy way to compare__eq__
between different representations of a weak tableau. - In the same vein, could we make it so that we can convert between different representations with parents? I.e. I'd like to do the following:
sage: T = WeakTableaux(3, [5,2,1], [1,1,1,1,1,1]) sage: T2 = WeakTableaux(3, [3,2,1], [1,1,1,1,1,1], representation='bounded') sage: T2(T[0])
- Could we have a method like
T.representation('bounded')
which returns the corresponding parent using a different representation. Same on the elements (which of course would call the respectiveto_*
method, but it would make it consistent IMO)? - I don't see an easy way to go to a factorized permutation from the other 2 representations. Right now it seems like I have to call
WeakTableau_factorized_permutation.from_core_tableau().
- I think the
from_*
(and quite possibly theto_*
) methods maybe should be available in the parents rather than as classmethods for the element classes. - The
.. SEEALSO::
block ink_charge()
is not formatting correctly, so it doesn't link the methods. - Could you use the
:arxiv:`1234.5678`
autolink? - Remove
self
as an input (ex. in
list_of_standard_cells()
)
Ack, that ended up being a longer list than I expected...
Best,
Travis

Hi Travis and Mike,
Thank you for your review comments. I incorporated them all, except for the input of the inner shape yet and the comments below:
- In the same vein, could we make it so that we can convert between different representations with parents? I.e. I'd like to do the following:
sage: T = WeakTableaux(3, [5,2,1], [1,1,1,1,1,1]) sage: T2 = WeakTableaux(3, [3,2,1], [1,1,1,1,1,1], representation='bounded') sage: T2(T[0])
We discussed coercing during design discussions at Sage Days 49 and currently decided against it. For now, it is easy to go between the various representations with the representation method. If we really need this feature, we can always add coercion later.
- I think the
from_*
(and quite possibly theto_*
) methods maybe should be available in the parents rather than as classmethods for the element classes.
This is what Nicolas suggested to me, so I will leave it as is.
Best,
Anne

Hi Mike,
Thanks for your review patch! I incorporated the changes. The new version now take as input
WeakTableaux(k, shape, weight, representation = 'core')
where shape is either a shape or a tuple of shapes in the skew case.
I hope everything looks ok now!

Hi Mike,
The updated patch incorporated all changes we discussed (by e-mail). It
- checks that the weight, shape, etc of the element agrees with its parent
- checks for semistandardness
- implements latex and pretty printing methods
- makes some changes Nicolas suggested
The semistandard checks and pretty printing rely on #14101, so I put this as a dependency.
Best,
Anne

Hi Mike,
I just posted a new version which incorporates your two doc review patches and fixes the bug in weights.

Fixed two more little issues that Mike found (spurious import of Tableau and innter_shape -> inner_shape).

Replying to zabrocki:
I'm happy and all tests pass.
Great, thank you for the review! I just made height_of_restriced_subword a private method. Nothing else changed.

See http://trac.sagemath.org/ticket/15444 for a follow-up on the k-charge implementation.
Strong tableaux was moved into ticket #14776
