Improved results for Klein-Gordon-Maxwell systems with general nonlinearity
This paper is concerned with the following Klein-Gordon-Maxwell system \begin{document}$\left\{ \begin{align} &-\vartriangle u+\left[ m_{0}^{2}-{{(\omega +\phi )}^{2}} \right]u = f(u),\ \ \ \ \text{in}\ \ {{\mathbb{R}}^{3}}, \\ &\vartriangle \phi = (\omega +\phi ){{u}^{2}},\ \ \ \ \text{in}\ \ {{\mathbb{R}}^{3}}, \\ \end{align} \right.$ \end{document} where $0 < ω≤ m_0$ and $f∈ \mathcal{C}(\mathbb{R}, …
