• The Green functions of the electrons in the two-band Hubbard model with thestrong on-site Coulomb repulsion were calculated by means of the perturbationtheory with respect to the hopping term of the Hamiltonian. It was shown that in theslave boson technique we obtain the expressions different from the results of thecalculations involving directly electron operators without using slave bosons. Thephysical meaning of this discrepancy was discussed.[strong correlation, slave boson, quasifermion, Hubbard model, high T. super- l% conductivity1
