A Rellich Type Theorem for Discrete Schr{ö}dinger Operators (1208.4428v2)
Published 22 Aug 2012 in math.SP
Abstract: An analogue of Rellich's theorem is proved for discrete Laplacian on square lattice, and applied to show unique continuation property on certain domains as well as non-existence of embedded eigenvalues for discrete Schr{\"o}dinger operators.
