Abstract
The motion of (interacting) holes in the Hubbard-Anderson model for hi gh-T(c) superconductivity is translated into the motion of (coupled) s pinless fermions. The entities responsible for the coupling are locali zed spin excitations and are described by bosons. The new description shows resemblance with the BCS description of electrons and phonons of the ''classical'' superconductors.
