Expansion of eigenvalues of the perturbed discrete bilaplacian
We consider the family [Formula: see text] of discrete Schrödinger-type operators in d-dimensional lattice [Formula: see text] , where [Formula: see text] is the discrete Laplacian and [Formula: see text] is of rank-one. We prove that there exist coupling constant thresholds [Formula: see text] such...
