Nodal solutions for fractional Schrodinger-Poisson problems

In this paper, we consider the following fractional Schrodinger-Poisson problem: {epsilon(2s)(-Delta)(s)u + V(x)u + phi u = vertical bar u vertical bar(p-1)u, x is an element of R-N, (-Delta)(t)phi = u(2), x is an element of R-N, where epsilon > 0 is a small parameter, N >= 3 and V(x) is a potential function. We construct non-radial sign-changing solutions, whose components may have spikes clustering at the local minimum point of V(x).
