Vogan diagrams of real forms of affine Kac-Moody Lie algebras

摘要

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 isomorphism classes of almost compact real forms.
