The Unbroken Spectra of Frobenius Seaweed Algebras
Journal of Lie Theory, Volume 33 (2023) no. 2, pp. 609-639
We show that if g is a Frobenius seaweed, then the spectrum of the adjoint of a principal element consists of an unbroken set of integers whose multiplicities have a symmetric distribution. Our methods are combinatorial.
