Chromatic symmetric functions and polynomial invariants of trees

José Aliste-Prieto, Jeremy L. Martin, Jennifer D. Wagner +1

Stanley asked whether a tree is determined up to isomorphism by its chromatic symmetric function. We approach Stanley's problem by studying the relationship between the chromatic s…

On the Spectra of Simplicial Rook Graphs

Jeremy L. Martin, Jennifer D. Wagner

The \emph{simplicial rook graph} SR(d,n) is the graph whose vertices are the lattice points in the $n$ th dilate of the standard simplex in $R^{d}$ , with two vertices adjacen…

Updown numbers and the initial monomials of the slope variety

Jeremy L. Martin, Jennifer D. Wagner

Let $I_{n}$ be the ideal of all algebraic relations on the slopes of the $(2 n)$ lines formed by placing $n$ points in a plane and connecting each pair of points with a line.…

On distinguishing trees by their chromatic symmetric functions

Jeremy L. Martin, Matthew Morin, Jennifer D. Wagner

Let $T$ be an unrooted tree. The \emph{chromatic symmetric function} $X_{T}$ , introduced by Stanley, is a sum of monomial symmetric functions corresponding to proper colorings of $T$ …
