20150603 16:55:46 +0200  asked a question  Dimensions of modules in branching For example, consider the following branching: How can I find the dimensions of all representations that occur? In this example, we obtain: and I would like to get: (Note: If I try A1(1).degree() I obtain 1 which is wrong.)

20130401 15:02:03 +0200  commented question  epsilon basis for roots (was graph edge labels) No the labels are in $\alpha$notation in SAGE. The matter is a bit more complicated since the $\epsilon$notation has to be computed from the $\alpha$notation. It;s just a different notation really. The problem is, that there's no $\epsilon$notation in SAGE, since the ambient space for RootSystem is implemented via tuples of numbers. 
20130401 11:43:19 +0200  asked a question  epsilon basis for roots (was graph edge labels) I need an illustration of some (sub)poset of positive roots. I have a working code that produces correct labels, but they are written as sums of simple roots. I.e. the resulting graph (when exported to LaTeX) has labels such as $\alpha_1 + \alpha_2$. I would like to have these labels in $\epsilon$notation. I.e. the previous example would read $\epsilon_1  \epsilon_3$. RootSystem has an ambient_space method that provides an access epsilon basis, but
