Descent polynomials

Alexander Diaz-Lopez, Pamela E. Harris, Erik Insko +2

Let $n$ be a nonnegative integer and $I$ be a finite set of positive integers. In 1915, MacMahon proved that the number of permutations in the symmetric group $S_{n}$ with…

Computing weight $q$ -multiplicities for the representations of the simple Lie algebras

Pamela E. Harris, Erik Insko, Anthony Simpson

The multiplicity of a weight $μ$ in an irreducible representation of a simple Lie algebra $g$ with highest weight $λ$ can be computed via the use of Kostant's weight mul…

The singular locus of semisimple Hessenberg varieties

Erik Insko, Martha Precup

Although regular semisimple Hessenberg varieties are smooth and irreducible, semisimple Hessenberg varieties are not necessarily smooth in general. In this paper we determine the i…

Peaks on Graphs

Alexander Diaz-Lopez, Lucas Everham, Pamela E. Harris +3

Given a graph $G$ with $n$ vertices and a bijective labeling of the vertices using the integers $1, 2, \dots, n$ , we say $G$ has a peak at vertex $v$ if the degree of $v$ is greater…
