摘要:
In this paper, we are concerned with superlinear fractional Schrdinger equation (-Delta)(s)u + V(x)u = f (x, u), x epsilon R-N, where f is continuous. When V and f are asymptotically periodic in x, we show the existence of ground states. When V and f are periodic in x, we obtain infinitely many geometrically distinct solutions. The method used here is based on the method of Nehari manifold and Lusternik- Schnirelmann category theory. (C) 2015 AIP Publishing LLC.
