Pseudogap phenomena in strongly correlated systems have essential spatial length scale dependence [M.V. Sadovskii, Physics -Uspekhi 44 (2001) 515]. To merge pseudogap physics and strong electron correlations we generalize the dynamical-mean field theory (DMFT) [A. Georges, G. Kotliar, W. Krauth, M.J
