Abstract: A new recursion method is proposed for the calculation of the thermodynamics of Ising-spin models with short range interaction. The method is exact in one dimensions, while for higher dimensions a truncation scheme is developed. The approach is tested in the two-dimensional Ising model. The results are within 0.7% of the exacr reduced free energy per spin.
