We study a p-Laplacian dierence equation on the set of integers, involving a coercive weight function and a reaction term satisfying the Ambrosetti-Rabinowitz condition. By means of critical point theory and a discrete maximum principle, we prove the existence of a positive homoclinic solution.

Abstract
We study a p-Laplacian dierence equation on the set of integers, involving a coercive weight function and a reaction term satisfying the Ambrosetti-Rabinowitz condition. By means of critical point theory and a discrete maximum principle, we prove the existence of a positive homoclinic solution.
