摘要: The aim of this paper is to establish the existence of at least two non-zero homoclinic solutions for a nonlinear Laplacian difference equation without using Ambrosetti-Rabinowitz type-conditions. The main tools are mountain pass theorem and Palais-Smale compactness condition involving suitable functionals.

关键词: Difference equations, homoclinic solutions, non-zero solutions, (p,q)-Laplacian operator
