Hi, >> I have a question about the Cartan type code: >> >> sage: C = CartanType(['A',4,2])
talking about Cartan types: I implemented QuiverMutationType to work with quivers and cluster algebras in http://trac.sagemath.org/sage_trac/ticket/10527. Those contain in particular all finite and affine types of Kac-Moody algebras as described in Kac's book (but beside that also multiple other types, and it is, and cannot be, exhaustive). As several affine types correspond to multiple quivers mutation types, a diffenent notion than in Kac's book is used, but those types can be inputed as well. It would be nice if someone could have a look at it at some point. I think, eventually we should have this very general type together with its "standard quiver", its Dynkin diagram, and its Coxeter graph, and Cartan type could take those objects from there. But this and other things are still to discuss properly... Regards, Christian -- You received this message because you are subscribed to the Google Groups "sage-combinat-devel" group.
