Nonnegative solutions for the degenerate logistic indefinite sublinear equation Original Research Article

The goal of this paper is to study the nonnegative steady-states solutions of the degenerate logistic indefinite sublinear problem. We combine bifurcation method and linking local subsupersolution technique to show the existence and multiplicity of nonnegative solutions. We employ a change of variable already used in a different context and the spectral singular theory to prove uniqueness results.
