Abstract
In this paper, we study the following fractional Schrödinger equation with electromagnetic fields and critical or supercritical growth
where \((-\Delta )_A^s\) is the fractional magnetic operator with \(0<s<1\), \(N>2s\), \(2_s^*=\frac{2N}{N-2s}\), \(\lambda >0\), \(V \in C(\mathbb {R}^N,\mathbb {R})\) and \(A \in C(\mathbb {R}^N, \mathbb {R}^N)\) are the electric and magnetic potentials, respectively. When V and f are asymptotically periodic in x, and f is a continuous function and there exists \(2< q<2_s^*\) such that \(|f(x,t)|\le C(1+|t|^{\frac{q-2}{2}})\) for all (x, t), for \( 2_s^*\le p<22^{*}_{s}-q\). For any \(D>0\) fixed, if \(\lambda \in (0,D]\) we prove that the equation has a nontrivial solution by the truncation method. Our method can provide a prior \(L^{\infty }\)-estimate.

Appendix
Appendix
In the present paper, we have constructed a \(C^{1}\) function \(\gamma (\cdot )\) which remedies the weakness in our paper [21, Lemma 2.2]. It is worth mentioning that in the present paper, we have resurfaced our results involving critical or supercritical results. And we caution readers that the truncation function \(\phi _{M}\) depends on M and some previous results (including [21, 29] and so on) need to be stated by another way. The authors thank the anonymous researchers for their useful discussions.
