Description (last modified by )
This patch implements reflection groups to work with finite (crystallographic, real, complex) reflection groups. It is based on the GAP3 package chevie.
sage: W = ReflectionGroup(['A',2],5,23); W Reducible complex reflection group of rank 7 and type A2 x ST5 x H3 sage: W.irreducible_components() [Irreducible real reflection group of rank 2 and type A2, Irreducible complex reflection group of rank 2 and type ST5, Irreducible real reflection group of rank 3 and type H3]
To install chevie
, one needs to download it from Jean Michel's website http://webusers.imjprg.fr/~jean.michel/gap3/, update some paths in GAP3_folder/bin/gap.sh
and make this file execute when typing gap3
inside the sage shell. I wouldn't think this is superhard to make an optional package as discussed at #8906.

I've rebased the patch and noticed that this will likely depend on #10963. I'll post a new version once I completely untangle what is going on with #10963.
I always made some minor changes on this patch locally  I would actually only start working on this patch after you guys are finished with #10963. If you want to actively work on this patch, ping me again, and we can discuss what is still needed to finilize this patch.
Cheers, Christian

Do you have a git branch for this ticket somewhere ? or should I try to resurrect the patch ?

Do you have a git branch for this ticket somewhere ? or should I try to resurrect the patch ?
No, I don't. But I have a local old version of Sage containing that code and quite a bit more, so I wonder if I should/will try to organize it a bit and put it up here.
Do you need any from that code in particular (in which case I am more tempted to work on that), or is that just a general question?
comment:18 Changed 5 years ago by
Hello, no, no real need for this code, just asking a general question. Now that #10963 is over.

Here's a git version of this patch with changes necessary to get Sage to start (I did not run any tests, so I am not saying things are working). There might be other changes to the files in question which need to be moved over too. Just as a general note from doing the rebasing, there are a bunch of methods missing doctests.

comment:44 Changed 4 years ago by
The current code gives
sage: C = ComplexReflectionGroups() sage: C.Irreducible() Category of complex reflection groups sage: C.Irreducible() is C True
Is that what you intended? Perhaps the "irreducible" axiom should be defined on ComplexReflectionGroups().Finite()
, not on ComplexReflectionGroups()
.
comment:45 Changed 4 years ago by
To summarise the discussion Christian and I just had: I believe WellGenerated
should be an axiom. Christian said that the general notion of wellgenerated is a bit tricky for infinite groups. Hence, he actually only wants to take into account wellgeneratedness for finite complex reflection groups.
Hence, the aim would be to define WellGeneratedComplexReflectionGroups
as application of an axiom to ComplexReflectionGroups.Finite
. However, I believe that the name should contain the word "finite" if we really want to focus on finite wellgenerated groups. Alternatively, it should be implemented as a nestednested class WellGenerated
within the nested class ComplexReflectionGroups.Finite
.
I also think that WellGeneratedComplexReflectionGroups
should provide a parent method _test_well_generated
that tests whether self
is wellgenerated. Such method would automatically be executed when running the test suite.
comment:46 Changed 4 years ago by
We have discussed already that in order to fix the Irreducible
axiom, it is needed (in addition to the nested class) to have a SubcategoryMethod
called Irreducible
.
Note that if we define WellGeneratedComplexReflectionGroups
as a subcategory of ComplexReflectionGroups.Finite()
, we should probably remove its subcategorymethods Finite
and Irreducible
, since both axioms have already been defined in the supercategory.

The iterators currently cache the list of all elements of the group. Is that (always) a good idea?

After discussion with Christian, the iterator of a complex reflection group is a lot faster. What we did was to keep ._reduced_word
as a list, and only transform it into an actual word when needed (i.e., in the .reduced_word()
method).
Before:
sage: G = ComplexReflectionGroup([2,1,4]) sage: %timeit L = list(G); G._elements=None The slowest run took 6.02 times longer than the fastest. This could mean that an intermediate result is being cached 1 loops, best of 3: 66.4 ms per loop
After:
sage: G = ComplexReflectionGroup([2,1,4]) sage: %timeit L = list(G); G._elements=None The slowest run took 66.44 times longer than the fastest. This could mean that an intermediate result is being cached 1 loops, best of 3: 5.56 ms per loop

Hi Christian,
This is not how the tests work:
def _test_well_generated(self, **options): tester = self._tester(**options) return self.is_well_generated()
Instead, do
def _test_well_generated(self, **options): tester = self._tester(**options) tester.assert_(self.is_well_generated())
or something similar.

@Simon and Nicolas: The category for complex reflection groups (with axioms finite/irreducible/wellgenerated) is now sort of ready. I would now like to make ComplexReflectionGroups().Finite().WellGenerated()
a super category of FiniteCoxeterGroups
.
 Is that what I should do?
 If I simply add a method
supercategories
toFiniteCoxeterGroups
, its string repr changes in a not desired way. How should I treat that?
Thanks, Christian

It sounds more like you want to add ComplexReflectionGroups().WellGenerated()
as a supercategory to CoxeterGroups
, in particular to replace Groups().FinitelyGenerated()
by ComplexReflectionGroups().WellGenerated()
. I also think ComplexReflectionGroups()
should be a subcategory of Groups().FinitelyGenerated()
(otherwise the additional axiom should go on the supercategory for CoxeterGroups()
). The finite part will take care of itself by the CategoryWithAxiom
magic.

Hello Christian, thanks for your hard work on this ticket. I have only had a quick look, so trivial remarks:
 not yet 100% coverage, I think (I have seen a few methods without examples)
TODO::
should be.. TODO::
 Could you please replace
Returns
byReturn
everywhere.  Sometime the first line of the doc is made of two sentences. Please separate them as:
Return something. Something is very very important.
 Please try to keep the lines 80 characters long.
 Bad alignement of EXAMPLES:: in
distinguished_reflection
,distinguished_reflections
 missing optional in
sage: W = CoxeterGroup(["A",4], implementation="chevie")
And you should aim to have a green light from the patchbot. So far, this has never been the case.

Thanks for having a look at this ticket!

I am aware of the stuff to do in the documentation, but before getting there (or, at least, in parallel, I'll fix your complaints now), I try to get the overall setting right (this includes the category framework, the interaction with other reflection group classes, and the dependence of chevie).
And you should aim to have a green light from the patchbot. So far, this has never been the case.
I'd like to get it green, but it has not run in 5 days, and I can only fix stuff the patchbot complaints about if I see its results regularly after uploading a new commit sequence (a patchbot that doesn't run soon after uploading doesn't really help during a coding sprint)...
Thanks again, Christian

There are many patchbots, but only one that has added all your participants to its trust list (at my demand). This one is currently not active. You can try to contact some active patchbots owners to ask them to trust the participants (see http://wiki.sagemath.org/buildbot/owners and http://patchbot.sagemath.org/machines). Or run your own patchbot.

Oh, I didn't know that all participants must be on the trust list, I thought it was only the submitter of the branch  I gonna try to get a patchbot running...
comment:90 Changed 4 years ago by
Yes, this comes from some difficulty to identify the true authors of the code..
For patchbot, please see the instructions there : http://wiki.sagemath.org/buildbot/details

I just started a patchbot recently, and I believe I now have it configured to trust all relevant participants and prioritize this ticket.
First run through wasn't very helpful, since I don't have Chevie installed. Though presumably everything should be marked with some kind of optional tag so that tests are skipped if Chevie isn't installed.
I'm in the process of trying to install Chevie, and if I succeed, I'll have it do another run.

I have Gap3/Chevie installed now.
It's probably easier (and a lot faster) to run
./sage t ./src/sage/combinat/root_system/reflection_group_complex.py
,
and if things are crashing and you need to see where, then do
./sage t verbose ./src/sage/combinat/root_system/reflection_group_complex.py
.
Patchbots are good for finding merge conflicts with new betas and seeing if you unintentionally broke other parts of Sage, but at this point I think it's sufficient to only test the one file you're changing with this ticket.
After playing around for a bit, something seems to be broken with the iterator. The example W = ReflectionGroup((1,1,3))
(should be isomorphic to S3) included as a test works fine, but if I try W = ReflectionGroup((3,1,1))
(should be isomorphic to cyclic group of order 3) then it keeps printing out the three elements in a neverending loop.

When adding new files, you should follow http://doc.sagemath.org/html/en/developer/coding_basics.html#headingsofsagelibrarycodefiles, in particular use the correct license statement.
comment:96 followup: ↓ 97 Changed 4 years ago by
Thanks for having a look here! I am currently working (since yesterday) on speeding the iteration through the group, I hope I have gotten somewhere later today...
I guess I must tag each and every test as
# optional  chevie
which means that these tests are not run on patchbots per default, or do they run if the patchbot has chevie installed?

Not literally every test, there are probably tests which do not require chevie
.
do they run if the patchbot has chevie installed?
They would be run if the Sage optional package chevie
is installed. However, such a package does not exist.

Replying to jdemeyer:

Every test (except for the creation of the category of complex reflection groups) handle with reflection groups (no surprise), and even initializing such a group requires chevie
.
But within finite time, I will work on making some core functionalities work without having chevie
installed.
They would be run if the Sage optional package
chevie
is installed. However, such a package does not exist.
Is that a problem? Should there be a possibility of installing chevie
as an optional package? I update the description of this ticket to explain how to get chevie installed in a system. See #8906 for old stuff about that.

It's not a problem for me or for this ticket. I guess it is a problem if people want to use the code that you are writing here, since getting chevie
to work within Sage is nontrivial.
