Hyperbolic subalgebras of hyperbolic Kac-Moody algebras

Anna Felikson, Pavel Tumarkin

We investigate regular hyperbolic subalgebras of hyperbolic Kac-Moody algebras via their Weyl groups. We classify all subgroups relations between Weyl groups of hyperbolic Kac-Mood…

Regular subalgebras of affine Kac-Moody algebras

Anna Felikson, Alexander Retakh, Pavel Tumarkin

We classify regular subalgebras of affine Kac-Moody algebras in terms of their root systems. In the process, we establish that a root system of a subalgebra is always an intersecti…
