The first eigencurve for a Neumann boundary problem involving p-Laplacian with essentially bounded weights

This article is intended to prove the existence and uniqueness of the first eigencurve, for a homogeneous Neumann problem with singular weights associated with the equation $ −\Delta_p u = \alpha m_1 |u|^{p−2} u + \beta m_2 |u|^{p−2} u $ in a bounded domain $ \Omega \subset \mathbb{R}^N $. We then establish many properties of this eigencurve, particularly the continuity, variational characterization, asymptotic behavior, concavity and the differentiability.
