Abstract:In this paper, we are concerned with the existence of at least three distinct solutions for a perturbed anisotropic discrete Dirichlet problem. The approach is based on variational methods. We also provide two examples in order to illustrate the results.
Keywords:Discrete boundary value problem  perturbed anisotropic problem  three solutions  variational methods  critical point theory
