Heisenberg Algebras from Division Algebras and Parabolic Subalgebras of Simple Lie Algebras
Journal of Lie Theory, Volume 28 (2018) no. 2, pp. 561-575
Every real simple Lie algebra which is not compact or isomorphic to so(1,n) contains a unique standard parabolic subalgebra whose nilradical is a Heisenberg-like algebra associated to a division algebra. Some geometric consequences are discussed.
