Symmetries of abelian ideals of Borel subalgebras

Paola Cellini, Pierluigi Moseneder Frajria, Paolo Papi

Published 2013-01-11, updated 2013-07-28Version 2

Elaborating on a paper by Suter, we provide a detailed description of the automorphism group of the poset of abelian ideals in a Borel subalgebra of a finite dimensional complex simple Lie algebra.
