An approximation of the pressure for the two-dimensional Ising model

Martin Janžura


A sequence of pressure functions corresponding to some one-dimensional models is used to approximate the pressure function of the two-dimensional Ising model. The rate of convergence is derived and the method is demonstrated with a numerical study.
