On the existence of positive solutions for an ecological model with indefinite weight

This study concerns the existence of positive solutions for the following nonlinear boundary value problem: {−Δu=am(x)u−bu2−cupup+1−Kin  Ω,u=0on  ∂Ω, where Δu=div(∇u) is the Laplacian of u, while a,b,c,p,K are positive constants with p≥2 and Ω is a bounded smooth domain of RN with ∂Ω in C2. The weig...
