Non-negative and positive solutions for some indefinite sublinear elliptic problems
Abstract
We study the existence of non-negative and positive solutions to the indefinite sublinear elliptic problem \(\ -\Delta u=\lambda u+m(x)\left \vert u\right \vert ^{\alpha -1}u\) in Ω, \(u=0\) on ∂ Ω, where Ω is a smooth bounded domain in \(\mathbb{R}^{N}\) , \(0
