In this article, we study the nonlinear fractional Schrodinger equation
where stands for the fractional Laplacian of order , , may change sign and f is only locally defined near the origin with respect to u. Under some new assumptions on V and f, we show that the above system has infinitely many solutions near the origin. Some examples are also given to illustrate our main theoretical result.
