It is establish regularity results for weak solutions of quasilinear elliptic problems driven by the well known Φ-Laplacian operator given byis a bounded domain with smooth boundary ∂Ω. Our work concerns on nonlinearities g which can be homogeneous or non-homogeneous. For the homogeneous case we consider an existence result together with a regularity result proving that any weak solution remains bounded. Furthermore, for the non-homogeneous case, the nonlinear term g can be subcritical or critical proving also that any weak solution is bounded. The proofs are based on Moser's iteration in Orclicz and Orlicz-Sobolev spaces. 2010 Mathematics Subject Classification. 35B65,35B09,35D30.
