%0 Journal Article %T On fractional Schr£żdinger equations in (\mathbb{R}^N) without the Ambrosetti-Rabinowitz condition %A Simone Secchi %J Mathematics %D 2012 %I arXiv %X In this note we prove the existence of radially symmetric solutions for a class of fractional Schr\"odinger equation in (\mathbb{R}^N) of the form {equation*} \slap u + V(x) u = g(u), {equation*} where the nonlinearity $g$ does not satisfy the usual Ambrosetti-Rabinowitz condition. Our approach is variational in nature, and leans on a Pohozaev identity for the fractional laplacian. %U http://arxiv.org/abs/1210.0755v2
