Abstract: The paper is concerned with the application of path integration (successive integration over “fast” and “slow” variables and the Hubbard–Stratonovich transformation) to the antiferromagnetic state in the three-band two dimensional repulsive Hubbard model. It is shown that the model under consideration is equivalent in the lowest approximation to the half–filled single–band Hubbard model. The effective action for the collective Bose-fields, the critical temperature of the phase transition and the exitations spectra are obtained.
