||We consider the problem
∆ p u = |u| p−2 u
= λ|u| p−2 u + g(λ, x, u) on ∂Ω,
where Ω is a bounded domain of R N 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.
