Fractional Schrodinger-Poisson Systems with a General Subcritical or Critical Nonlinearity

We consider a fractional Schrodinger-Poisson system with a general nonlinearity in the subcritical and critical case. The Ambrosetti-Rabinowitz condition is not required. By using a perturbation approach, we prove the existence of positive solutions. Moreover, we study the asymptotics of solutions for a vanishing parameter.
