Abstract: We are concerned with the mathematical and asymptotic analysis of solutions to the following nonlinear problem −ΔAu=λβ(x)|u|qu+f(|u|)uin Ω,u=0on ∂Ω, where ΔAu is the magnetic Laplace operator, Ω⊂RN is a smooth bounded domain, A:Ω↦RN is the magnetic potential, u:Ω↦C, λ is a real parameter, β∈L∞(Ω,R) is an indefinite potential, q is nonnegative, and f:[0,+∞)↦R is a reaction that oscillates either in a neighborhood of the origin or at infinity. We analyze two distinct cases, in close relationship with the oscillatory growth of the reaction. Additionally, we give asymptotic estimates for the norm of the solutions in related function spaces.

Keywords: Magnetic Laplace operator, blow-up, low- and high-energy solutions, oscillation, variational methods
