Abstract
It is establish regularity results for weak solutions of quasilinear elliptic problems driven by the well known \(\Phi \)-Laplacian operator given by
where \(\Delta _{\Phi }u :=\hbox {div}(\phi (|\nabla u|)\nabla u)\) and \(\Omega \subset \mathbb {R}^{N}, N \ge 2,\) is a bounded domain with smooth boundary \(\partial \Omega \). 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 Orlicz and Orlicz-Sobolev spaces.
