Positivity and anti-maximum principles for elliptic operators with mixed boundary conditions

We consider linear elliptic equations $- Δ u + q (x) u = λ u + f$ in bounded Lipschitz domains $D \subset ℝ^{N}$ with mixed boundary conditions $\partial u / \partial n = σ (x) λ u + g$ on $\partial D$ . The main feature of this boundary value problem is the appearance of $λ$ both in the equation and in the boundary condition. In general we make no assumption on the sign of the coefficient $σ (x)$ . We study positivity principles and anti-maximum principles. One of our main results states that if $σ$ is somewhere negative, $q \geq 0$ and $\int_{D} q (x) d x > 0$ then there exist two eigenvalues $λ_{- 1}$ , $λ_{1}$ such the positivity principle...
