The author has developed a method of statical fluctuations applied to Hubbard model and nanosystems. The given model enables to calculate anticommutator Green functions of Hubbard for two sublattices model, hexagon, pentagon and dimer. It is shown that a concentration of electrons for sites of different Hubbard two sublattices model is distinguished.

Hubbard model, Green functions, energy spectrum, nanosystems, hexagon, pentagon and dimer.
