摘要: It is conjectured that the singularities in free energy for q-state Potts model on square lattice lie two self-dual circles complex x plane where x=exp(-J/kT) usual low-temperature variable. These are natural generalisations of known Ising (q=2). The conjecture leads to prediction there a single antiferromagnetic critical point at x=1+(q/(q-1))12/.
