ON NEGATIVE EIGENVALUES OF THE DISCRETE SCHRÖDINGER OPERATOR WITH NON-LOCAL POTENTIAL

Sh.S. Lakaev, Z.E. Muminov


On the d-dimensional lattice Zd ,d = 1,2 the discrete Schrödinger operator μ H with
non- local potential constructed via the Dirac delta function and shift operator is considered. The
existence of negative eigenvalues on the parameters of the operator is explicity derived
