THE NUMBER OF EIGENVALUES OF THE DISCRETE SCHRÖDINGER OPERATOR

Akhmadova Mukhayyo Olimjon qizi


In this paper we consider the family  of Schrödinger operators, associated to the Bose-Hubbard Hamiltonian of   a single boson on the one dimensional lattice  . We find suffiently conditions for the parameters , such that  the operator  has no one eigenvalues below the essential spectrum and three eigenvalues above the essential spectrum.
