Hi all, I have coded for myself some functions to plot weight diagrams: a ranked, directed graph whose vertices are the weights of a representation and whose edges are the simple roots connecting them. It shows the multiplicities of the weights too. Here is how it looks like for the adjoint representation of A2: http://dl.dropbox.com/u/80518046/adj_of_A2.png
As this is something I would have liked to have found implemented in Sage, I would humbly suggest to include it, I guess after some more or less heavy polishing. Maybe as a method of a member of a Weyls character ring? The relevant functions and some examples are in a worksheet here: http://dl.dropbox.com/u/80518046/Plotting%20weight%20diagrams.sws I did my best with optimization, specially in weight_graph. I am kind of proud of it all :) Cheers, Jesús Torrado -- You received this message because you are subscribed to the Google Groups "sage-combinat-devel" group.
