摘要：

We study an eigenvalue problem in the framework of difference equations. We show that there exist two positive constants lambda(0) and lambda(1) verifying lambda(0) <= lambda(1) such that any lambda is an element of (0, lambda(0)) is not an eigenvalue of the problem, while any lambda [lambda(1), infinity) is an eigenvalue of the problem. Some estimates for lambda(0) and lambda(1) are also given.
