Abstract
We investigate the effect of an incipient ferrolectric transition on vertex
corrections to the superconducting pairing interaction. The vertex correct
ions for small momentum transfers are largely independent of the type of bo
son responsible for the superconducting transition. The electron-phonon int
eraction is found to be enhanced by a nearly ferroelectric medium. We discu
ss application to the cuprate superconductors.
