Abstract
Electron and phonon spectra are derived for an electron-phonon system coupled by the Frohlich interaction. We cover the range from small cou pling lambda<1 to large coupling lambda >> 1 for a commensurate fillin g of the bare band. The evolution of the Migdal solution into a charge density wave and
