Positive ground state solutions for the critical Klein-Gordon-Maxwell system with potentials

Subcritical and supercritical Klein-Gordon-Maxwell equations without Ambrosetti-Rabinowitz condition

“…In [4], the authors Azzollini and Pomponio showed that system (1) admits a ground state solution with subcritical exponents q in the range 2 < q < 6. Taking into account [4], Carrião, Cunha & Miyagaki [8] proved the existence of positive ground state solutions for the critical Klein-Gordon-Maxwell system with a potential V , namely,…”
