Improved results of nontrivial solutions for a nonlinear nonhomogeneous Klein–Gordon–Maxwell system involving sign-changing potential
Abstract This paper is concerned with the following system: { − Δ u + λ A ( x ) u − K ( x ) ( 2 ω + ϕ ) ϕ u = f ( x , u ) + h ( x ) , x ∈ R 3 , Δ ϕ = K ( x ) ( ω + ϕ ) u 2 , x ∈ R 3 , $$ \textstyle\begin{cases} {-\Delta u+\lambda A(x) u-K(x)(2 \omega +\phi ) \phi u=f(x, u)+h(x), \quad x \in \mathbb{...
