Abstract
The free energy and the correlation functions are proved to be analytic functions of the inverse temperature β, the external magnetic field H, and the impurity probability p, provided the temperature is high enough and the spin‐spin interaction has finite range. In particular, this excludes spontaneous magnetization at high temperatures.Keywords
