On Negative Eigenvalues Of The Discrete Schrödinger Operator With Non-Local Potential, Sh.S. Lakaev, Z.E. Muminov
Scientific Journal of Samarkand University
On the d- dimensional lattice 2 , 1 , d d Z the discrete Schrödinger operator 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.
