Abstract
In this paper, we prove that (−∞,0) is a zero-free interval for chromatic polynomials of a family L0 of hypergraphs and (0,1) is a zero-free interval for chromatic polynomials of a subfamily L0′ of L0 of hypergraphs. These results extend known results on zero-free intervals of chromatic polynomials of graphs and hypergraphs.
