Abstract:
The two-orbital Hubbard modet with degeneracy and isotropic hopping integrals is
considered. A systematic method is proposed for taking into account iutra-atomic
correlations of the electrons by means of generalized Okubo tensor operators. The
spectrum of electron excitations in a very simple case is calculated as an example.
