We present some monotonicity and symmetry results for positive solutions of the equation - div D u p - 2 D u = f u satisfying an homogeneous Dirichlet boundary condition in a bounded domain Ω . We assume 1 < p < 2 and f locally Lipschitz continuous and we do not require any hypothesis on the critical set of the solution. In particular we get that if Ω is a ball then the solutions are radially symmetric and strictly radially decreasing.
