摘要：

By applying the holon-doublon formalism to a highly correlated system consisting of d- and p-electrons, a theory is developed concerning whether a superconductive phase can be realized in parallel to the previously investigated single-band model. The result follows: those d-states hybridized with (partially occupied) p(sigma+)-band form pairs and are condensed into superconductive ground state. On this model almost all features characteristic to hole-doped, layer-structured high T(c) superconductors are, at least qualitatively, interpreted.
