Asymptotic normality of Laplacian coefficients of graphs

Yi Wang, Haixia Zhang, Baoxuan Zhu

Let $G$ be a simple graph with $n$ vertices and let $C (G; x) = k = 0 \sum n (- 1)^{n - k} c (G, k) x^{k}$ denote the Laplacian characteristic polynomial of $G$ . Then if the size $∣ E (G) ∣$ is l…

Polynomials with palindromic and unimodal coefficients

Hua Sun, Yi Wang, Hai-Xia Zhang

Let $f (q) = a_{r} q^{r} + \dots + a_{s} q^{s}$ , with $a_{r} \neq = 0$ and $a_{s} \neq = 0$ , be a real polynomial. It is a palindromic polynomial of darga $n$ if $r + s = n$ and $a_{r + i} = a_{s - i}$ for all $i$ . P…
