Abstract

A tight-binding system of 3d9 and 2p6 electrons is considered in the framework of a polar model for metals. By applying the Green function method an equation for a superconducting gap is derived. It is pointed out that high-Tc in metal oxides can be caused by highly anharmonic oxygen vibrations and by kinematic attraction of electrons due to the strong single-site Coulomb correlations.
