摘要：
The leading term for the electronic self-energy in a 1/N expansion due to an on-site electron-phonon interaction is calculated for Hubbard models with infinite U. The resulting modifications of the Eliashberg function are discussed and calculated for a square lattice in the continuum approximation.
