2012-03-05 Thread Viviane Pons
Hi, About your bug, I don't know if someone is looking after SchubertPolynomialRing, from what I see it is mostly sent to symmetrica. I see what is causing the problem, when creating an element, the index is sent to Permutation_class which doesn't check if the list is a valid permutation. When I

2012-03-05 Thread Viviane Pons
It will also slow things for SchubertPolynomialRing if we do the check for each new element. The problem is that when the permutation is not correct and someone try to expand the polynomial, then instead of doing a usual exception, it stops the program ! I think it comes from something with symmetr

[sage-combinat-devel] Default basis ring for ambient space

Hi everyone, I just noticed that the default basis ring for ambient space has been changed to cyclotomic field. I don't know the reason behind that but it doesn't seem handy ! In my case, I use the elements of the ambient space to index another combinatorial free module and it is a pain that thei

Ok, well in the mean time I will force the field to be QQ on my hand. But I think a long end solution would be to do some test on the root system type to decide what is the best field. Cheers Viviane 2012/5/8 Christian Stump : > Hi Viviane, > >> This type of thing just broke my entire patch on m

Non symmetric mac donald polynomials are also implemented in sage-combinat in a more general patch on multivariate polynomials. This is done by Lascoux's formula using divided differences, but as I am not a specialist I have not tested this part much. You can see how the whole patch work on my web
