    Abstract

    The motion of (interacting) holes in the Hubbard-Anderson model for high-Tc superconductivity is translated into the motion of (coupled) spinless fermions. The entities responsible for the coupling are localized spin excitations and are described by bosons. The new description shows resemblance with the BCS description of electrons and photons of the ¿classical¿ superconductors.
