摘要：

We have addressed the problem of anisotropic superconductivity within the two-dimensional Hubbard model extended by phonon-mediated pairing Correlations. The Hubbard I approximation has been used to account for the formation of the insulating gap and to see the role of Coulomb correlations for superconducting pairing. It has been shown that phonon-free and phonon-induced mechanism can cooperate in the stabilization of superconductivity in the d-wave channel.
