 Volume 9, Number 2, 2019, Pages 628-637 Multiple solutions for a nonhomogeneous Schrodinger-Poisson system with concave and convex nonlinearities Lixia Wang,Shiwang Ma Keywords:Schrodinger-Poisson systems, concave and convex nonlinearities, variational methods, Ekeland's variational principle, Mountain Pass Theorem. Abstract: In this paper, we consider the following nonhomogeneous Schrodinger-Poisson equation $$\left\{ - \Delta u +V(x)u+\phi(x)u =-k(x)|u|^{q-2}u+h(x)|u|^{p-2}u+g(x), &x\in \mathbb{R}^3,\\ \Delta \phi =u^2, \quad \lim_{|x|\rightarrow +\infty}\phi(x)=0, & x\in \mathbb{R}^3, \right.$$ where \$1 PDF      Download reader
