[sage-combinat-devel] Hopf algebra methods

2012-07-24 Thread Daniel Bump
The symmetric function patch #5457 is a big step towards being able to work with the Hopf algebra of symmetric functions. Here's an interesting fact. Recall that the elements of the symmetric function Hopf algebra can be interpreted as representations of the symmetric group. For example, the Schu

Hi All! I guarded Mark's patch for sage-5.2.rc0 since he will only be able to rebase it next week. The queue should now apply also for sage-5.2.rc0, but a lot of patches had to be guarded. Please check the queue to see whether your patch is marked #+5_2_rc0 needs rebase on 5_2_rc0!!! and pleas

Anne, I have been able to get this to apply to 5.2.rc0 clean. I haven't tried it with the combinat queue. I assume the errors you are posting from when this is applied to the combinat queue? I'm just trying to install it now. -Mike On Friday, 20 July 2012 01:57:47 UTC-4, Anne Schilling wrote: >
