On zero-free intervals of flow polynomials

Journal of Combinatorial Theory, Series B, 2015
This article studies real roots of the flow polynomial $F(G,λ)$ of a bridgeless graph $G$. For any integer $k\ge 0$, let $ξ_k$ be the supremum in $(1,2]$ such that $F(G,λ)$ has no real roots in $(1,ξ_k)$ for all graphs $G$ with $|W(G)|\le k$, where $W(G)$ is the set of vertices in $G$ of degrees larger than $3$. We prove that $ξ_k$ can be determined by
