Subalgebras of Hyperbolic Kac-Moody Algebras
Alex J. Feingold, Hermann Nicolai
The hyperbolic (and more generally, Lorentzian) Kac-Moody (KM) Lie algebras $\cA$ of rank are shown to have a rich structure of indefinite KM subalgebras which can be des…

Fusion Rules for Affine Kac-Moody Algebras
Alex J. Feingold
This is an expository introduction to fusion rules for affine Kac-Moody algebras, with major focus on the algorithmic aspects of their computation and the relationship with tensor…

Type A fusion rules from elementary group theory
Alex J. Feingold, Michael D. Weiner
We show how the fusion rules for an affine Kac-Moody Lie algebra g of type A_{n-1}, n = 2 or 3, for all positive integral level k, can be obtained from elementary group theory. The…
