| Abstract: | We investigate the high-temperature correlation functions of the ferromagnetic Ising model on a plane rectangular lattice Λ with external field h. The only further restrictions on the interactions are: a) translational invariance b) the range is a unit rectangle. We compare our results with Ornstein-Zernicke theory. |
