Abstract: |
In this paper, we study the existence of ground state solutions for SchrödingerMaxwell equations {-△u +V(x)u+K(x)ϕ(x)u=b(x)|u|p-1u+λg(x,u) in R3, -△ϕ=K(x)u2 in R3, where λ > 0, V (x) ∈ C1(R3, R) and V (x) > 0.Under certain assumptions on K, g and 0 < p < 1, we obtain the ground state solutions by using variational methods and critical point theory, which promotes the results of literature[7]. |
