Hodge-Riemann relations for Potts model partition functions
P. Brändén, and J. Huh. (2018)cite arxiv:1811.01696Comment: 7 pages.
Abstract
We prove that the Hessians of nonzero partial derivatives of the (homogenous)
multivariate Tutte polynomial of any matroid have exactly one positive
eigenvalue on the positive orthant when $0<q1$. Consequences are proofs of
the strongest conjecture of Mason and negative dependence properties for
$q$-state Potts model partition functions.
