Unusual analytic properties of some lattice models: Complement of Lee–Yang theory

S. B. Shlosman


Abstract: Problems of the analytic dependence of the free energy of “Czech” models on the interaction parameters are studied. It is shown that the free energy is an analytic function although the complex zeros of the partition function have real values of the interaction parameters as their limit points.
