| 摘 要： | In this article, we study the following fractional Schr?dinger equation with electromagnetic fields and critical growth (-?)_A~su + V(x)u = |u|~(2_s~*-2) u + λf(x, |u|~2)u, x ∈ R~N,where(-?)_A~s is the fractional magnetic operator with 0 s 1, N 2s, λ 0, 2_s~*=2N/(N-2s),f is a continuous function, V ∈ C(R~N, R) and A ∈ C(R~N, R~N) are the electric and magnetic potentials, respectively. When V and f are asymptotically periodic in x, we prove that the equation has a ground state solution for large λ by Nehari method.
