[sage-combinat-devel] UCF breaking cartan types in 5.7beta4
I'm running sage 5.7 beta4 and the entire combinat queue applies but a lot of functionality is broken. sage -t combinat/root_system/cartan_type.py got 89 failures. I think they stem from UCF being imported but not defined. -- You received this message because you are subscribed to the Google Groups sage-combinat-devel group.

+1 for having a FEM implementation.

So, there is much to do (which is great)... t.d. Since it is a normal python package, the first step of integrating this into sage is to package it as an experimental SPKG. Then, it is at least very easy to install. Fully agree, I did not have making a simulation part of the standard in mind. As I said, I created a personal experimental package and integrated it ito one of my Sage installs. This is absolutly sufficient for my personal use. However, if the community thinks it is worthwhile I would put it up for review. Christian -- You received this message because you are subscribed to the Google Groups sage-devel group.

[sage-devel] Re: What can we change on a parent?
On Feb 11, 11:30 pm, Robert Bradshaw rober...@math.washington.edu wrote: I don't think we should have a separate ZZ whose category is EuclideanDomains another one whose category is Rings, another one whose category is AbelianGroups, and another one whose category is Sets. Perhaps this is a special case, as this is a nested set of subcategories. Absolutely. I think that is more a matter of choosing which objects we actually want to be able to construct. Actually, 1 dimensional free ZZ- modules and infinite cyclic abelian groups already exist for good reason, as special cases of more general constructions, so basically we already have these. I would propose that (1) every method (within reason) whose result depends on the category take a category as an argument and (2) for most (but perhaps not all) methods this defaults to the category in which the element was constructed, regardless of specializations that are later discovered. Perhaps this could be (partially) enforced with a decorator for such methods. Indeed. In particular, it means that a parent knows in which category it was originally created. I think that's the important observation here (the rest is a matter of how to best make use of the information available). This is because: 1) Parents are supposed to model category object and as such HAVE a category of which they are a member. This category is part of their identity. 2) Parents must be immutable because they are shared. Therefore this category cannot change. In addition, parents may keep track of their refined category which reflects additional structure discovered during computations. It may well be that this refined category plays a more important role internally because it is useful in method dispatch. Currently refined category is called _category and I don't think we're tracking the creation category. Perhaps we don't have to store it explicitly if it is recoverable via other means, but I doubt it. The in my opinion more logical naming scheme would be category and refined_category. However, if for compatibility reasons this has to be _creation_category and _category instead, I think that would be acceptable. I concur with Robert that it's quite reasonable to have methods that can inquire about the properties of a parent in a category other than its creation category. Logically that's just a composition with a functor. In most cases the functor application by itself would serve little purpose, so we can just store the composition. I'm not so sure that parametrizing by category leads to particularly efficient and nice code. Different method names may work there as well. It would be the generic routine (if required) that has to dispatch by creation_category then. I suspect that in practice category refinement will be a relatively rare occurrence, with probably rather minimal effects. However, if we're going to allow for it we'll have to specify clear semantics for it. -- You received this message because you are subscribed to the Google Groups sage-devel group.

[sage-devel] Please test this if you have OS X 10.8
Hi! Thanks to very hard work by Ivan Andrus, we have Sage double-clicking sws files on Mac. We just need one more test to make it complete. If you DO have OS X 10.8 Mountain Lion but have NOT ever made something that makes sws files open with Sage.app on a double-click, please download http://sage.math.washington.edu/home/palmieri/misc/sage-Sage-testing-doubleclick-x86_64-Darwin.dmg and try it out. We particularly would like people who don't even have Sage.app to try this, since with multiple versions of Sage.app there can be natural confusion as to which one is supposed to open the file, though in principle this should work there as well.
