Description
We developed such an approach for the Hubbard model with the strong one-site Coulomb interaction U. We study a structure of GFs in both the fermion and boson sectors. In the last case, we deal with GFs of magnons (collective motion of a spin deviation) and doubloons (the collective motion of a pair of electrons on a site as a complex)
