Modified Erdös--Ginzburg--Ziv Constants for $Z / n Z$ and $(Z / n Z)^{2}$

Aaron Berger, Danielle Wang

For an abelian group $G$ and an integer $t > 0$ , the \emph{modified Erdös--Ginzburg--Ziv constant} $s_{t}^{'} (G)$ is the smallest integer $ℓ$ such that any zero-sum sequence of lengt…

The Eulerian distribution on involutions is indeed $γ$ -positive

Danielle Wang

Let $I_{n}$ and $J_{n}$ denote the set of involutions and fixed-point free involutions of ${1, \dots, n}$ , respectively, and let $des (π)$ denote the number o…

On roots of Wiener polynomials of trees

Danielle Wang

The \emph{Wiener polynomial} of a connected graph $G$ is the polynomial $W (G; x) = \sum_{i = 1}^{D (G)} d_{i} (G) x^{i}$ where $D (G)$ is the diameter of $G$ , and $d_{i} (G)$ is the number of pa…
