摘要

In this paper, we consider the following nonlinear Schrödinger-Poisson system[ left{ enewcommand{rraystretch}{1.25} egin{array}{ll} -Delta u + V(x)u+K(x)phi u= f(x,u), xin mathbb{R}^3, -Delta phi=K(x)u^{2}, xin mathbb{R}^3, end{array} ight.]where~(V, Kin L^{infty}(mathbb{R}^3)) and (f:mathbb{R}^3imesmathbb{R}ightarrowmathbb{R}) is continuous. We prove that the problem has a nontrivial solution under asymptotically periodic case of (V, K), and (f) at infinity. Moreover, the nonlinear term (f) does not satisfy any monotone condition.
