On zero-free regions for the anti-ferromagnetic Potts model on bounded-degree graphs

Ferenc Bencs, Ewan Davies, Viresh Patel +1

For a graph $G=(V,E)$, $k\in \mathbb{N}$, and a complex number $w$ the partition function of the univariate Potts model is defined as \[ {\bf Z}(G;k,w):=\sum_{ϕ:V\to [k]}\prod_{\su…
