Let 0 < q 1 p . In this study, we investigate positive solutions of the logistic elliptic equation − Δ u = ( ) in a smooth bounded domain Ω R N , ≥ with nonlinear boundary condition ∂ ν λ on This arises from coastal fishery harvesting. We prove that there exists at least one solution for every > case Furthermore, when is subcritical, exist two sufficiently small but no large enough Here, smalle...
