SPECTRAL ASYMPTOTICS OF DISCRETE SCHRÖDINGER OPERATORS UNDER POINT INTERACTION POTENTIALS"
We investigate the one-particle discrete Schrödinger operator with Dirac delta potential on the -dimensional lattice. We show that the operator the operator has a unique eigenvalue and obtain an asymptotics expansion for this eigenvalue as wight of potential approaches the infinity.
