The Emery three-band model, extended with Ox-Oy hopping tpp, and with Ud tending to infinity, is mapped on slave fermions. The Dyson time-dependent diagrammatic theory in terms of the Cu-O hopping tpd, which starts from the nondegenerate unperturbed ground state, is translationally and asymptotically locally gauge invariant. The small parameter of the theory is nd. The lowest order of the theory generates the single particle propagators of the hybridized pdp- and dpd-fermions with the exact three band structure.
