摘要：

The n-electron ground state of the Friedel resonance model can be written as a single Slater determinant of n s-electrons plus one d-electron-s-hole companion. This new formula is derived geometrically in the Hilbert space. The derivation uses che fact that a it-electron Slater determinant, built fi om N band states, corresponds to a n-dimensional subspace in the N-dimensional Hilbert space.
