[sage-combinat-devel] base rings in SFA

Hi, I am having some issues with the base rings using Schur's Q functions. I am beginning to think that they may need to be made a separate basis rather than a t=-1 specialization of the HallLittlewoodQ, but maybe there is just too much that I am not following about how they work. Here is my

Hi there, I think Sage documentation is quite good, but with a big flaw: it is widely missing for cross links. Many classes and methods could greatly benefit from a SEE ALSO section. I would like to advertise for this... If patch writer and reviewer tries to more or less

I'm guessing that CPPFLAGS should also be preserved by sage-env. Similar to CXXFLAGS and LDFLAGS, it's typically used to pass include options to the C preprocessor. -- To post to this group, send an email to sage-devel@googlegroups.com To unsubscribe from this group, send an email to
