Abstract
The properties of the Hubbard-Holstein model for an electron-phonon sy stem with strong electron correlations are investigated on. the basis of a new diagram technique. The equations of the main dynamical quanti ties and optical dispersionless phonons are established. The problem o f excluding partially or completely the phonon's coordinates and the c orresponding renormalization of the physical parameters of the theory is discussed.
