We study the nonlinear eigenvalue problem −Δ p u=λm(x)|u| p−2 u in Ω. ∂u/∂n=0 on ∂Ω, where p>1. For ∫ Ω m(x)<0, we prove that the first positive eigenvalue λ 1 exists and is simple and unique, in the sense that it is the only eigenvalue with a positive eigenfunction. In the case ∫ Ω m(x)=0, we prove that λ 0 =0 is the only eigenvalue with a positive eigenfunction
