[sage-combinat-devel] Re: tensor products of free modules; combinatorial algebras

2014-03-11 Thread Mark Shimozono
Nicolas, Does it make sense to have a particular abstract object in an abstract category in sage and be able to work with it and describe its properties, all on the abstract level? What I have in mind is the unit object in the tensor category of modules. I have this working concretely (tensors

Hey everyone, I've been using #10963 in developing #14901 (Lie algebras). I first gave 'Lie' as an axiom of NonAssociativeNonUnitalAlgebras (which I just asked Nicolas for how to do it without really looking at the examples), but decided that I didn't want _mul_() to give the Lie bracket, so

On that note, I think reviewers shouldn't hold up tickets because they don't like the current implementation without providing a working alternative and can demonstrate why it's better. Do you think that a patch should automatically be merged when it has been waiting for a reviewer for a

Hey John no worries, I was only answering Travis' post and this (rethorical) question was just meant as a way to show that I did not concur with his view that reviewers should have to implement their remarks when the review gets long. Nathann On Tuesday, 11 March 2014, John H Palmieri

Helloo ! I agree with John. I actually think Nicolas is quite patient trying to answer all questions. You are so kind. My suggestion would be either for Volker to implement his alternative on a different ticket, so we can see it in action and test it, or to let Nicolas' patch go in

Paul, Instead, I would advocate using a declarative domain specific language built for semi-formalizing mathematics The appeal of this paradigm is evident. It addresses a fundamentally important issue: how to structure the development process to encourage the code to reflect the mathematics
