In this paper we prove a lemma about the Weyl groups of Kac᎐Moody algebras and decompose the Weyl group of some Kac᎐Moody algebras into a semi-direct product of two subgroups which are Coxeter groups.

The theory of Vogan diagrams, which are Dynkin diagrams with an overlay of certain additional information, allows one to give a rapid classification of finitedimensional real semisimple Lie algebras and to make use of this classification in practice. This paper develops a corresponding theory of Vog
A Vogan diagram is actually a Dynkin diagram with some additional structure. This paper develops theory of Vogan diagrams for "almost compact" real forms of indecomposable nontwisted affine Kac-Moody Lie algebras. Here, the equivalence classes of Vogan diagrams are in one-one correspondence with the
