摘要：
We discuss phonon-induced anisotropic superconductivity of strongly correlated quasiparticles within the two-dimensional Hubbard model. The generalized Frolich-like canonical transformation leads to pairing interactions that become repulsive for vanishing concentration of holes but are attractive at low dopings. Our results indicate that the electron-phonon coupling in the presence of strong electron-electron correlations favors the formation of d-wave superconductivity.
