This paper deals with semilinear elliptic problems of the type −Δu + α(x)u = β(x)|u|p−1u in RN, u(x) >0 inRN, u ∈ H1(RN), where p is superlinear but subcritical and the coefficients α and β are positive functions such that α(x) → a∞ > 0 and β(x) → b∞ > 0, as |x| → ∞. Aim of this work is to describe some phenomena that can occur when the coefficients are “competing.”

Abstract
This paper deals with semilinear elliptic problems of the type −Δu + α(x)u = β(x)|u|p−1u in RN, u(x) >0 inRN, u ∈ H1(RN), where p is superlinear but subcritical and the coefficients α and β are positive functions such that α(x) → a∞ > 0 and β(x) → b∞ > 0, as |x| → ∞. Aim of this work is to describe some phenomena that can occur when the coefficients are “competing.”File in questo prodotto:
