Abstract:
The properties of Hubbard–Holstein model for electron-phonon system with strong electron correlations were investigated on the base of new diagram technique. The equations of the main dynamical quantities and optical dispersionless phonons were established. The problem of excluding partially or completely of phonon's coordinates and the corresponding renormalization of the physical parameters of the theory was discussed.
