Non-ordering conjecture for fuzzy Potts measures on the lattice

Let q3q\geq 3, r1,,q1r\in \\{1,\dots,q-1\\}, and consider the fuzzy Potts model on Zd\mathbb{Z}^d. For J>0J>0, write νq,J,rZd,+\nu_{q,J,r}^{\mathbb{Z}^d,+} for its plus-state fuzzy Potts measure, and let stochastic ordering be the usual ordering of probability measures on configurations. Non-ordering conjecture. If J1,J2>0J_1,J_2>0 with J1J2J_1\neq J_2, then νq,J1,rZd,+\nu_{q,J_1,r}^{\mathbb{Z}^d,+} and νq,J2,rZd,+\nu_{q,J_2,r}^{\mathbb{Z}^d,+} are not stochastically ordered. This conjecture concerns the failure of monotonicity in the interaction parameter; the corresponding statement for the Ising model is proved, while the fuzzy Potts case is presented as open.
