Abstract: | In this paper, we prove that is a zero-free interval for chromatic polynomials of a family of hypergraphs and is a zero-free interval for chromatic polynomials of a subfamily of of hypergraphs. These results extend known results on zero-free intervals of chromatic polynomials of graphs and hypergraphs. |
