Resumo

His paper is devoted to the study of nonlinear difference phi Laplacian problems with periodic boundary value conditions. Using known results that assure the existence of solutions for the considered problems, we obtain sufficient conditions in the nonlinear part of the equations that allow us to define a lower and an upper solution for the treated problems and deduce existence of solutions.
