We study an asymptotically linear Schr¨odinger equation in the whole Euclidean space RN. By using a suitable linking theorem we prove that the problem admits not only the trivial solution but also either a sign–changing solution or one positive and one negative solution.

Abstract
We study an asymptotically linear Schr¨odinger equation in the whole Euclidean space RN. By using a suitable linking theorem we prove that the problem admits not only the trivial solution but also either a sign–changing solution or one positive and one negative solution.File in questo prodotto:
