Synopsis

Usage:

Outputs:
- g, an instance of the type LieAlgebra, the simple Lie algebra with the given rank and type

Description

The classification of simple Lie algebras over the complex numbers is well known. There are four infinite families (types $\mathfrak{a}_n$, $\mathfrak{b}_n$, $\mathfrak{c}_n$, $\mathfrak{d}_n$) corresponding to the Lie algebras $\mathfrak{sl}(n+1,\mathbb{C})$, $\mathfrak{so}(2n+1,\mathbb{C})$, $\mathfrak{sp}(2n,\mathbb{C})$, $\mathfrak{so}(2n,\mathbb{C})$ respectively, and five exceptional simple Lie algebras, $\mathfrak{e}_6$, $\mathfrak{e}_7$, $\mathfrak{e}_8$, $\mathfrak{f}_4$, $\mathfrak{g}_2$.
