Abstract The chain of the BBGKY (Bogolyubov‐Born‐Green‐Kirkwood‐Yvon) equations for lattice systems is obtained. These equations differ greatly from those for the continuous case and can be used in the theory of the Ising model. Different characteristics of ordering in alloys are computed using these equations: phase transition temperature, correlation parameter, correlation functions at great distances. The results obtained are in good agreement with other theories.
