This can be the lengthy awaited follow-up to Lie Algebras, half I which lined an important a part of the idea of Kac-Moody algebras, stressing essentially their mathematical constitution. half II bargains in most cases with the representations and functions of Lie Algebras and comprises many go references to half I. The theoretical half principally bargains with the illustration concept of Lie algebras with a triangular decomposition, of which Kac-Moody algebras and the Virasoro algebra are major examples.
