Summary

We show that, under appropriate structure conditions, the quasilinear Dirichletproblem(− div(|∇u|p−2∇u) = f(x, u), x ∈ Ω,u = 0, x ∈ ∂Ω,where Ω is a bounded domain in Rn, 1 < p < +∞, admits two positive solutions u0, u1in W1,p0(Ω) such that 0 < u0 ≤ u1 in Ω, while u0 is a local minimizer of the associatedEuler-Lagrange functional
