Three-electron first doublet in the impurity Hubbard model

We consider the energy operator of a three-electron systems in the impurity Hubbard model and investigate the structure of essential spectra and discrete spectrum of the system in the first doublet state on the $$\nu$$ -dimensional lattice.
