Root system data for type A infinity¶
-
sage.combinat.root_system.type_A_infinity.
CartanType
¶ The Cartan type \(A_{\infty}\).
We use
NN
andZZ
to explicitly differentiate between the \(A_{+\infty}\) and \(A_{\infty}\) root systems, respectively. Whileoo
is the same as+Infinity
in Sage, it is used as an alias forZZ
