Abstract
The approximation of statistical fluctuations is considered as applied to the Hubbard model. The expressions are obtained for the Green func tions, magnetization and concentration of the system. The expression a re compared with exact solution in atom limit and exact solution of on e-dimensional Hubbard's model when T = 0.
