In this paper, we study the following Schrödinger–Poisson system { −∆u + V(x)u + φu = f (x, u) + g(x), x ∈ R3, −∆φ = u2, x ∈ R3. Under appropriate assumptions on V, f and g, using the Mountain Pass Theorem and the Ekeland’s variational principle, we establish two existence theorems to ensure that the above system has at least two different solutions. Recent results from the literature are extended and improved.
