Vogan diagrams of twisted affine Kac–Moody Lie algebras
A Vogan diagram is a Dynkin diagram of a Kac-Moody Lie algebra of finite or affine type overlayed with additional structures.This paper develops the theory of Vogan diagrams for "almost compact" real forms of indecomposable twisted affine Kac-Moody Lie algebras and shows that equivalence classes of Vogan diagrams correspond to …
