ABELIAN IDEALS IN A COMPLEX SIMPLE LIE ALGEBRA
Published online by Cambridge University Press: 10 June 2016
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.
