We mainly consider the systemwhere Ω ⊂ R N is a bounded domain, p(x) is a function which satisfies some conditions, − p(x) u = −div(|∇u| p(x)−2 ∇u) is called p(x)-Laplacian. We give the existence of positive solutions under some conditions. In particular, we do not assume radial symmetric conditions on the system.
