“…Using the monotonicity trick and global compactness Lemma, Teng proved the existence of a nontrivial ground state solution for the system where . By the perturbation method, Li studied the above system for the case V ( x )=1, see previous studies and so on. To the best our knowledge, there is little information on the existence of solution for fractional Schrödinger‐Poisson system in the case .…”
