Abstract
Using a one-band Hubbard model with infinite U and an on-site electron -phonon interaction it is shown that electronic correlations produce a strong forward scattering peak in the effective electron-phonon coupl ing. As a result, the electron-phonon interaction responsible for tran sport is heavily suppressed whereas that causing pair formation is onl y changed in a minor way.
