## Positive solutions for some non-autonomous Schrödinger-Poisson systems.(English)Zbl 1183.35109

Summary: We study the Schrödinger-Poisson system
$\begin{cases} -\Delta u+u+K(x) \varphi(x)u= a(x)|u|^{p-1}u, &x\in\mathbb R^3,\\ -\Delta\varphi= K(x)u^2, &x\in\mathbb R^3, \end{cases}$
with $$p\in(3,5)$$. Assuming that $$a:\mathbb R^3\to\mathbb R$$ and $$K:\mathbb R^3\to\mathbb R$$ are nonnegative functions such that
$\lim_{|x|\to\infty} a(x)= a_\infty>0, \qquad \lim_{|x|\to\infty} K(x)=0$
and satisfying suitable assumptions, but not requiring any symmetry property on them, we prove the existence of positive solutions.
