摘要：
In this paper, we consider the following nonhomogeneous Schrodinger-Poisson equation (*) {-Delta u + V(x)u + phi(x)u = -k(x)vertical bar u vertical bar(q-2)u + h(x)vertical bar u vertical bar(p-2)u + g(x), x is an element of R-3, -Delta phi = u(2), lim(vertical bar x vertical bar -> +infinity) phi(x) = 0, x is an element of R-3, where 1 < q < 2, 4 < p < 6. Under some suitable assumptions on V(x), k(x), h(x) and g(x), the existence of multiple solutions is proved by using the Ekeland's variational principle and the Mountain Pass Theorem in critical point theory.
