Abstract:
In this article, we prove the existence of homoclinic solutions for
a p(.)-Laplacian difference equation on the set of integers,
involving a coercive weight function and a reaction term satisfying
the Ambrosetti-Rabinowitz condition. The proof of the main result is
obtained by using critical point theory combined with adequate variational
techniques, which are mainly based on the mountain pass theorem.
