 Title: Zero-free intervals of chromatic polynomials of hypergraphs Authors: Subjects: GraphHypergraphChromatic polynomial Issue Date: 2020 Citation: Zhang, R., & Dong, F. (2020). Zero-free intervals of chromatic polynomials of hypergraphs. Discrete Mathematics, 343(12), Article 112134. https://doi.org/10.1016/j.disc.2020.112134 Abstract: In this paper, we prove that $\left(-\infty ,0\right)$ is a zero-free interval for chromatic polynomials of a family ${\mathcal{L}}_{0}$ of hypergraphs and $\left(0,1\right)$ is a zero-free interval for chromatic polynomials of a subfamily ${\mathcal{L}}_{0}^{\prime }$ of ${\mathcal{L}}_{0}$ of hypergraphs. These results extend known results on zero-free intervals of chromatic polynomials of graphs and hypergraphs. Description: This is the final draft, after peer-review, of a manuscript published in Discrete Mathematics.
