In the present paper, we consider the following discrete Schrödinger equations where is a continuous function and is a positive potential, , and is the one dimensional discrete Laplacian operator. Under some suitable assumptions on , we prove the existence of nontrivial solutions for this nonlocal problems by variation methods.
