Abelian ideals in a complex simple lie algebra

Research output: Contribution to journalArticlepeer-review

Abstract

In this note, we give a new simple construction of all maximal abelian ideals in a Borel subalgebra of a complex simple Lie algebra. We also derive formulas for dimensions of certain maximal abelian ideals in terms of the theory of Borel de Siebenthal.
