Improved bounds for zeros of the chromatic polynomial on bounded degree graphs

Maurizio Moreschi, Viresh Patel, Guus Regts +1

We prove that for any graph $G$ of maximum degree at most $Δ$ , the zeros of its chromatic polynomial $χ_{G} (z)$ (in $C$ ) lie outside the disk of radius $5.02Δ$ centered at…

S-parts of values of univariate polynomials

Maurizio Moreschi

Let $S = {p_{1}, \dots, p_{s}}$ be a finite non-empty set of distinct prime numbers, let $f \in Z [X]$ be a polynomial of degree $n \geq 1$ , and let $S^{'} \subseteq S$ be the subset of…
