A positive solution of asymptotically periodic Schrödinger equations with local superlinear nonlinearities
In this paper, we investigate the following Schrödinger equation −∆u + V(x)u = λ f(u) in R N, where N ≥ 3, λ > 0, V is an asymptotically periodic potential and the nonlinearity term f(u) is only locally defined for |u| small and satisfies some mild conditions. By using Nehari manifold and Moser i...

| Tartalmi kivonat: | In this paper, we investigate the following Schrödinger equation −∆u + V(x)u = λ f(u) in R N, where N ≥ 3, λ > 0, V is an asymptotically periodic potential and the nonlinearity term f(u) is only locally defined for |u| small and satisfies some mild conditions. By using Nehari manifold and Moser iteration, we obtain the existence of positive solutions for the equation with sufficiently large λ. |
