Abstract
We consider the stationary nonlinear magnetic Choquard equation
where \({N \geq 3, \alpha \in (0, N), p \in \bigl[2, \frac{2N - \alpha}{N - 2}\bigr), A : \mathbb{R}^N \rightarrow \mathbb{R}^N}\) is a magnetic potential and \({W : \mathbb{R}^N \rightarrow \mathbb{R}}\) is a bounded electric potential. For a given group \({\Gamma}\) of linear isometries of \({\mathbb{R}^N}\), we assume that A(gx) = gA(x) and W(gx) = W(x) for all \({g \in \Gamma, x \in \mathbb{R}^N}\). Under some assumptions on the decay of A and W at infinity, we establish the existence of solutions to this problem which satisfy
where \({\phi : \Gamma \rightarrow \mathbb{S}^1}\) is a given continuous group homomorphism into the unit complex numbers.
