The unbroken spectra of Frobenius seaweeds

Alex Cameron, Vincent E. Coll, Matthew Hyatt +1

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 s…

On compositions associated to seasweed subalgebras of sl(n)

Vincent E. Coll, Aria Dougherty, Matthew Hyatt +2

A standard seaweed subalgebra of $A_{n - 1} = sl (n)$ may be parametrized by a pair of compositions of the positive integer $n$ . For all $n$ and certain $k (n)$ , we provide cl…

The classification of 231-avoiding permutations by descents and maximum drop

Matthew Hyatt, Jeffrey Remmel

We study the number of 231-avoiding permutations with $j$ -descents and maximum drop is less than or equal to $k$ which we denote by $a_{n, 231, j}^{(k)}$ . We show that $a_{n,231,j}^{…
