The density function theorem is proven that there is a unique one-to-one cor-respondence at the absolute zero temperature between the density of f electrons andthe depth of f levels. The ground state properties such as the Kondo temperature,and ttte charge ana spin susceptibilities are calculated ror infinitely large Coulombcorrelation, and they are expressed in terms of the density instead of the depth.An application to a lattice Anderson Hamiltonian (or the dense Kondo state)is briefly discussed; the correction due to nearly empty excited f multiplets issmall enough to be ignored in the critical number of occupied f electrons for therealization of the dense Kondo state; the critical number is very close to unity.
