The absolute values of the perfect matching derangement graph's eigenvalues almost follow the lexicographic order of partitions

Meiqiao Zhang, Fengming Dong

In 2013, Ku and Wong showed that for any partitions $μ$ and $μ^{'}$ of a positive integer $n$ with the same first part $u$ and the lexicographic order $μ ◃ μ^{'}$ , the eigenva…

Compare list-color functions of uniform hypergraphs with their chromatic polynomials (II)

Meiqiao Zhang, Fengming Dong

For any $r$ -uniform hypergraph $H$ with $m$ ( $\geq 2$ ) edges, let $P (H, k)$ and $P_{l} (H, k)$ be the chromatic polynomial and the list-color function of $…
