Bifurcation from the first eigenvalue of the p-Laplacian with nonlinear boundary condition
MetadataShow full metadata
We consider the problem Δpu = |u|p-2u in Ω, |∇u|p-2 ∂u/∂v = λ|u|p-2u + g(λ, x, u) on ∂Ω, where Ω is a bounded domain of ℝN with smooth boundary, N ≥ 2, and ∆p denotes the p-Laplacian operator. We give sufficient conditions for the existence of continua of solutions bifurcating from both zero and infinity at the principal eigenvalue of p-Laplacian with nonlinear boundary conditions. We also prove that those continua split on two, one containing strictly positive and the other containing strictly negative solutions. As an application we deduce results on anti-maximum and maximum principles for the p-Laplacian operator with nonlinear boundary conditions.
