Abstract
We investigate the effect of an incipient ferrolectric transition on vertex corrections to the superconducting pairing interaction. The vertex corrections for small momentum transfers are large independent of the type of Boson responsible for the superconducting transition. The electron-phonon interaction is found to be enhanced by a nearly ferroelectric medium. We discuss application to the cuprate superconductors.
