Remarks on infinitely many solutions for a class of Schrödinger equations with sign-changing potential

Abstract In this paper, we study the existence of infinitely many nontrivial solutions for the following semilinear Schrödinger equation: { − Δ u + V ( x ) u = f ( x , u ) , x ∈ R N , u ∈ H 1 ( R N ) , $$ \textstyle\begin{cases} -\Delta u+V(x)u=f(x,u), \quad x\in\mathbb{R}^{N},\\ u\in H^{1}(\mathbb{...
