About: En (Lie algebra)

An Entity of Type: WikicatLieGroups, from Named Graph: http://dbpedia.org, within Data Space: dbpedia.org

In mathematics, especially in Lie theory, En is the Kac–Moody algebra whose Dynkin diagram is a bifurcating graph with three branches of length 1, 2 and k, with k = n − 4. In some older books and papers, E2 and E4 are used as names for G2 and F4.
