Non-ordering conjecture for fuzzy Potts measures on the lattice
Non-ordering conjecture for fuzzy Potts measures on the lattice
Let , , and consider the fuzzy Potts model on . For , write for its plus-state fuzzy Potts measure, and let stochastic ordering be the usual ordering of probability measures on configurations. Non-ordering conjecture. If with , then and 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.
