Abstract
A model for copper-oxide metals with large local repulsion on copper and Coulomb interaction between ions is solved systematically to get the leading low-energy behavior of physical properties. The one-particle spectra is of a marginal Fermi liquid at the density where mean-field solutions display a valence degeneracy of copper ions. The metallic state is unstable to superconductivity with an electronic energy scale.
