AB - <p>We study the existence of solutions for the Schrödinger-Poisson system $-Δu+u+k(x)φu=α(x)|u|^{p-1}u$, in $R^3$,&nbsp; $-Δφ=k(x)u^2$, in $R^3$, where 3 ≤ p &lt; 5, α(x) is a sign-changing function such that both the supports of α^+ and α^- may have infinite measure. We show that the problem has at least one nontrivial solution under some assumptions.</p>
